All right!
The WoW D&D book looks like it will have some really interesting and innovative designs in an effort to replicate the feeling of WoW within D&D. I'm going purely on the information from Insight Check's video about the monster design, which only gave us a couple of (fairly generic) stat blocks, but the details about the blocks he couldn't actually show suggests that the book is going to have some really interesting fights, including the use of Mythic phases to replicate the feeling of a multi-phase WoW boss fight.
Speaking of bosses: the 30 "dungeon boss" stat blocks are not on this list. Presumably, we'll have figures like High Inquisitor Whitemane or Onyxia detailed in that earlier chapter. While I'd love to have an array of memorable bosses from outside of the seven included dungeons, I'm going to avoid getting my hopes up and just assume that we'll be getting the ones that go specifically with Dire Maul, Deamines, etc. The dungeons they picked are generally quite good (I don't really care much about Blackfathom Deeps, but I'll be curious to see how they handle it). Still feels like we should have gotten Hogger as a CR 1 legendary monster.
(Brief aside: Hogger was the objective of an infamous quest in Elwynn Forest, the human starting zone. He's the leader of a group of gnoll bandits. But he's also the first "elite" creature many players came across when first playing the game, which are designed to be fought in a group and not alone. Players who didn't realize that they were meant to take him on with friends died in droves, giving this fairly nondescript gnoll creature a legendary status as a peerless and savage killer. In Cataclysm, they largely reworked group quests at low levels to be something you could complete on your own, but while players would face Hogger in more or less the same circumstances in Elwynn, the quest ended not with you killing him, but having him arrested. Then, in the Stormwind Stockades dungeon, he became the dungeon's final boss, leading a prison riot. While he was intended to be a challenge for players just about ready to move on from Elwynn around level 10, players have also formed 40-player raid groups of level 1 characters to fight him as well.)
Anyway, let's not beat around the bush and look at the list:
CR 1: Fel Imp, Murloc Forager, Voidwalker
CR 2: Shadowstalker Satyr
CR 3: Murloc Oracle, Voidcaller
CR 4: Felguard, Felsworn Satyr, Furbolg Totemic
CR 5: Felhound, Furbolg Ursa, Naga Myrmidon
CR 6: Green Dragonflight Whelp
CR 7: Blue Dragonflight Whelp, Naga Sea Witch, Quillboar Thornweaver
CR 8: Red Dragonflight Whelp
CR 9: Black Dragonflight Whelp, Naga Siren
CR 10: Bronze Dragonflight Whelp
CR 11: Doomguard, Moonkin, Nerubian Warrior
CR 12: Abomination, Green Dragonflight Drake, Infernal
CR 13: Blue Dragonflight Drake, Nerubian Crypt Fiend
CR 14: Ancient of War, Nerubian Venomancer
CR 15: N'raqi Faceless One, Red Dragonflight Drake
CR 16: Black Dragonflight Drake, Shivarra
CR 17: Bronze Dragonflight Drake
CR 19: Green Dragonflight Dragon
CR 20: Anduin Wrynn, Blue Dragonflight Dragon, Pit Lord
CR 21: Alleria Windrunner, N'raqi Faceless General, Red Dragonflight Dragon
CR 22: Black Dragonflgiht Dragon, Jaina Proudmoore, Thrall
CR 23: Bronze Dragonflight Dragon, Ragnaros, Sylvanas Windrunner
CR 24: Illidan Stormrage
CR 25: Lich King Arthas
That's actually an impressive spread of CRs. Particularly, it's interesting to see certain monster categories like N'raqi only showing up at quite high levels. I do find it interesting that the Bronze dragons are the most powerful, given that in theory, the Red dragons are the "leaders" of the dragonflights (though the Dragon Aspects are pretty egalitarian, even if there's deference toward Alexstrasza, the Red aspect, who is basically the most benevolent living creature on Azeroth, sometimes to a fault.
Rather than spread out across all the expansions with all their different monster types, it looks like they've focused on a few iconic categories, which is probably wise even if it would have been cool to get, say, Titanforged constructs or something.
There are also a few individual people, and it's pretty impressive that they start at CR 20, though given how superheroic characters in WoW tend to be, that's not terribly shocking.
But let's go category by category here for those who are unfamiliar with WoW terms.
Demons:
Demons in WoW are pretty much all associated with the Burning Legion, an apocalyptic army under the command of the rogue Titan Sargeras who seek to burn the universe to cinders rather than let it fall to corruption by the Void. (Demonic Fel magic is also corrupting, but think of this as, like, nuking the world to try to save it from horrible mutations.) While the Fel is inherently chaotic, the Legion itself is actually a bit more Lawful Evil, given Sargeras' leadership over it, and sees the madness of the deeply chaotic Void to be the ultimate enemy. Demons include the Fel Imp, Felguard, Felhound, Doomguard, Infernal, Shivarra and Pit Lord. While the Felsworn Satyr and Shadowstalker Satyr are also demons (satyrs are former Night Elves turned demons in WoW,) they sort of may or may not be affiliated with the Legion, as they're more likely to be associated with the Emerald Nightmare, which is actually a phenomenon created by the Void-affiliated Old Gods. Xavius, the first satyr, fought on behalf of the Legion during the War of the Ancients ten thousand years ago, but after the Legion's defeat, he got in good with the Old Gods. Another little asterisk here is that Voidwalkers were long considered demons (they're one of the minions that player Warlocks can summon, and are great for soloing as they basically tank for you) but over time, and as Blizzard has honestly just locked down their lore a bit tighter, Voidwalkers are now generally considered aberrations affiliated with, weirdly enough, the Void.
Murlocs:
Among the most iconic and beloved (/hated) WoW creatures, Murlocs are silly little fish people. Honestly, not too far off from Kuo-toa, though less weird god-creating powers and more just being silly little guys who tend to be tightly-packed so that it's hard to pull just a single one at a time (this was a bigger problem when soloing out in the world was harder). Unofficially the mascots of World of Warcraft, they had to show up here.
Void/Old God Creatures:
So, there's a bit of a divide here. The Void is one of the great cosmic forces in WoW, and while there are benign aspects to it as a source of mystery and cosmic possibility, we usually interact with it as an antagonistic force - the "mystery" often leading to "horrifying abominations" and the yawning darkness of the void being more ravenous and consuming than an invitation to explore. Notably, beings called the Void Lords (only one of which we've actually had named, Dimensius, who honestly just looks like a massive Voidwalker, and was the final boss of 2024's The War Within expansion) send globs of void energy to Azeroth, which took on a physical form to become the Old Gods, eldritch, Lovecraftian flesh-mountains who spawned countless servitors. The Old Gods ultimately settled on Azeroth and created their dystopian Black Empire. Thus, Void-associated monsters come in two pretty distinct categories: ethereal blue/purple energy beings, which I'd say include Voidwalkers and Voidcallers, and then the more fleshy tentacle monsters like the N'raqi, which we see with the Faceless One and the Faceless General. (As a note, the Faceless General is likely technically a C'thraxxi, which are often associated with the N'raqi, but I think might be their own species. When both monsters were introduced in Wrath of the Lich King, they were both simply referred to as "faceless ones," and only later did we get these proper noun terms).
Furbolgs:
Yes, that's not a typo, and Furbolgs are actually distinct from Firbolgs. Furbolgs are Bear people. That's about it. Just essentially sapient bears. They can be friendly or hostile, and are often affected a lot by whatever is happening to the natural world around them. Generally found in forested lands.
Naga:
When the War of the Ancients ended and the destruction of the Well of Eternity led to the Sundering of the ancient Pangea-like continent of Kalimdor (the western regions of which retain that name,) the Night Elf Queen Azshara, the greatest mage to ever live on Azeroth, watched as her capital city was about to be consumed by the rushing ocean (Azshara had allied with the invading Burning Legion, so it was partially her fault). Desperate to survive along with her loyal Highborne followers, she accepted a deal from the Old God N'zoth, who transformed her and her people into aquatic, serpentine monsters called Naga. For the next ten thousand years, Azshara rebuilt her empire under the waves. Naga forces periodically raid the surface, and might seem to be just a threat to sailors and fishers, but they're basically the de facto superpower of the ocean depths.
Dragons:
Dragons in WoW are a bit different from those in D&D. For one thing, broadly speaking, dragons were originally all pretty much good guys, though the Dragonflight expansion complicates that narrative a bit. Originally elemental beings who evolved into living creatures of flesh, the Titanforged Keeper Tyr allied with a group of proto-drakes to fight a dire threat, and upon recognizing their power, "uplifted" them to become the five Dragon Aspects, created modern dragons and having each become demigod-like beings who would sire broad draconic clans known as Dragonflights. The five flights are the Red, Blue, Bronze, Black, and Green. Each was given a domain over which they were supposed to serve as protectors: Red Dragons over life itself, Blue over magic, Black over the deep places under the world's surface, Green over the natural world, and Bronze over time itself. Among the Aspects, Alexstrasza was the most beloved and served as their leader, the Dragon Queen. Infamously, though, during the War of the Ancients (but sort of unrelated to the Legion's invasion,) Neltharion, the Black Aspect, was driven mad by the Old Gods and consumed with a desire to wreak utter chaos upon the surface of Azeroth. This madness spread to nearly all the Black Dragons as a sort of infectious corruption. Other flights have periodically played antagonistic roles: the Blues at one point turning on mortal spellcasters, Green dragons affected deeply by the Emerald Nightmare, and weird alternate-timeline Infinite Dragon versions of the Bronzes fighting to split the timeline into countless branches.
Quillboar:
Strange that we just get a single Quillboar statblock. These are weird sort of boar-people that also have porcupine-like spines on their backs. Never really front-and-center, they're basically always hostile, though don't seem to be inherently evil on a fundamental level.
Nerubians:
The Nerubians are spider-folk who were once vassals to the Old Gods' Black Empire. While a humanoid people in and of themselves, our first exposure to them (and where we're likely to see them the most) is after the Nerubian kingdom of Azjol-Nerub was conquered by the Scourge. Thus, the undead armies of the Scourge often have undead Nerubians among their ranks.
Moonkin:
Weirdly sort of WoW's take on Owlbears, but only very loosely, Moonkin are considered favored creations of the Night Elves' Moon Goddess, Elune, and walk upright with bear-like bodies and owl-like beaks (though no wings other than their feathered arms). Possessing very rudimentary intelligence, they also have the power to call upon astral and lunar magic, and are the preferred form for Druids who wish to focus on offensive spellcasting (there's guidance that if you want to play a Balance Druid, you can take Circle of Stars and just flavor your constellation forms as a Moonkin instead).
Abomination:
One of the most fearsome and gross weapons of the Undead Scourge, Abominations are massive flesh-golems with several arms and tend to wield hooked chains.
Ancients:
Ancients are basically Treants, sapient trees that are often allied with Night Elves and help protect their settlements or fight in their wars.
Individuals:
There are several named characters here. I won't go into a whole biography, but here's the basic rundown:
Anduin Wrynn: The young king of Stormwind after the death of his father Varian during the final Legion invasion. Anduin is a priest/cleric and deeply kind but also has experienced a lot of trauma.
Alleria Windrunner: Former Ranger-General of the High Elves, she left with the Alliance expedition to Outland and, thanks to weird time-warping, spent a thousand years fighting against the Burning Legion. During this time, she cultivated a connection with the Void, using its dark cosmic power in the fight against evil, which makes things... complicated with her husband Turalyon, one of the most devout paladins wielding the Holy Light.
Jaina Proudmoore: Now Grand Admiral of Kul Tiras (effectively the head of state of this deeply nautical nation,) Jaina is also one of the most powerful living mages. Allying with the Horde during the Third War, and ultimately allowing her father to be killed to save the nascent Orcish nation of Durotar survive, this act was thanked with the destruction of the city-state of Theramore that she had founded by an aggressive Horde, which has put her at both extremes of Alliance-Horde relations. Also, she was close friends with Arthas Menethil before he fell to evil (the characters in these games have lived through a lot of trauma).
Thrall: Former Warchief of the Horde, and one of the greatest living Shamans, Thrall was actually the first Orc ever born on Azeroth. Liberating his people from their internment camps they were put in following the Second War, he became a beacon of hope for Orcs who wished to see a Horde free of demonic corruption, but when he stepped down as Warchief and named the hot-headed and, well, honestly, fascistic asshole Garrosh Hellscream as his successor, he found himself weighed down by the erroneous decisions he had made as a leader. Now, basically a private citizen of the Horde but with a lot of power and influence, Thrall mostly tries to live as a family man with his two kids and wife.
Ragnaros: The Elemental Lord of Fire, Ragnaros is staggeringly ancient, having existed pretty much as long as Azeroth. Embodying fire's drive to spread and consume, Ragnaros is a force of pure destruction, and was the boss of WoW's very first raid, The Molten Core. (He would also be the boss of The Firelands later on, when he was killed permanently within the plane of fire).
Sylvanas Windrunner: Sister of Alleria, Sylvanas took over for her older sister as Ranger-General of Quel'thalas right in time for the Undead Scourge, led by Arthas, to carve a path of death and terror through her homeland, killing off 90% of the High Elf population, including her. Arthas personally tore her soul from her body to turn her into a banshee, though she later found her own corpse and possessed it. When the Frozen Throne weakened, Sylvanas was among the first to regain her free will, and led an attempted assassination against Arthas, driving the future Lich King from the Plaguelands. She then rallied the free-willed Undead to become the Forsaken, serving as their "Banshee Queen." However, while she had regained her free will, any semblance of morality had more or less drained out of her, and her rule as Banshee Queen was marked by atrocities. Sylvanas is one of those characters who see-saws between antihero and full-on villain.
Illidan Stormrage: The first Demon Hunter, Illidan was a lowborn Night Elf and twin to Malfurion, who would go on to become the first Druid. Illidan was ambitious, and worked his way up through the ranks of Queen Azshara's mages despite his lack of aristocratic status. When the Legion invaded and Azshara's elite partook of their fel powers, Illidan feigned collaboration but instead used his position to learn all he could about the power that the Legion held and found a way to use it against them. While he played a crucial role in defeating the Legion, many still thought of him as a collaborator, earning him the epithet of The Betrayer. For his crimes, he was imprisoned for ten thousand years, only freed during the Third War so that his expertise could be used again. Truly WoW's most classic antihero, Illidan is ruthlessly pragmatic and makes bold moves that many will... not agree with, though his goals are ultimately for the greater good.
Arthas Menethil: WoW's most iconic villain, Arthas Menethil was the Crown Prince of Lordaeron and protege to the first Paladin (well, the first human paladin,) Uther the Lightbringer. However, his actions when the Scourge began to ravage his kingdom led him to acts of reckless violence and callousness that many would argue showed he had already fallen to evil before he gave his soul to the runeblade Frostmourne. However, with the evil sword in hand, Arthas fully lost his humanity and became a Death Knight, acting as the Scourge's mightiest champion. Ascending the Frozne Throne following his victory over Illidan Stormrage (why Illidan was there is... too complicated for here,) Arthas merged with the Lich King, absorbing Ner'zhul's mind into his own to become the sovereign of the undead and one of the greatest threats Azeroth has ever faced.
