What is the Blue Child?

The Moon figures prominently in the folklore of many of Azeroth's inhabitants. The Night Elves of course associated or perhaps equate it with Elune, their moon goddess. We still don't really know Elune's nature, but we do know that she exists and is powerful at least on a scale with Titans and Naaru.

The Tauren consider the moon the Night Elves call Elune to be Mu'sha, one of the two "eyes of the Earth Mother" with the Sun, An'she, being the other. In Shu'halo (the Taurahe word for Tauren) myth, these two figures are their own entities while at the same time being connected to the supreme being, the Earth Mother (which in my headcanon is the Titan Azeroth - it hasn't been confirmed, but the fact that Azeroth literally has a living god inside of it seems to line up pretty concretely with the myth of the Earth Mother.)

The dichotomy of the Sun and Moon is pretty commonplace on Azeroth - the only two female Mogu were sort of themed on the Sun and the Moon. The High Elves built their society around the two foci of the Sunwell and Silvermoon City. Balance Druids are all about balancing the Nature/Life magic of the Sun with the Arcane magic of the Moon. It's a theme.

But Azeroth has a second moon. And no one seems to pay any attention to it.

The two moons of Azeroth are typically called the "White Lady" and the "Blue Child." The White Lady gets most of the attention - in fact, the "Lady" in question is very likely the Goddess Elune - while Night Elves lived in isolation for a long time, it's clear that some of their culture filtered into human society through the High Elves as well as perhaps some small remnants in the Eastern Kingdoms.

The only potential common reference to it is in what I have generally assumed to be a critical research failure when writing voice lines for Worgen NPCs. Often when you click on a Worgen or Gilnean human, they'll say "May the Light of the New Moon Guide You." To anyone who remembers learning about moon phases in elementary school, this is a really silly-sounding line. The New Moon is the phase in which the moon is between the Earth and the Sun, and thus the side that faces earth is entirely in the moon's own shadow, so that there's no moonlight (and in fact, during the New Moon, it's only up during the day anyway.) The Full Moon is when the moon is brightest because it's on the opposite side of the earth from the sun, and so we see the entire earth-facing side illuminated by the sun.

The full moon is of course what we usually associate with werewolves - in fact, there's a statistic that emergency rooms fill up with more injuries on a full moon, though this isn't because of men transforming into beasts, but rather because the extra light mean people are staying out later and getting drunker (fine, they're also getting mauled by lycanthropes.)

So clearly this sounds like some shoddy copy-editing that no one caught until it was too late to feasibly fix it.

But if we want to get super wonky and explain it away (like the way that we got an entire movie to explain why Han Solo described his famous "Kessel Run" in units of distance rather than time,) might we argue that the moon the Worgen are referring to is actually the Blue Child?

Sure, it does seem like their werewolf moon-associations would really be based on Elune (consider it was the Scythe of Elune that created the modern Worgen form,) but if we run with this admittedly flimsy premise, might the "New Moon" have a different meaning on Azeroth?

Consider, for example, that neither moon seems to have phases. Sure, Balance Druids have a spell that plays with phases and again this might be a real-world technical issue rather than something true in-game. But if the moons don't have phases, what, then, does New Moon refer to?

If it means the Blue Child, does that suggest that the Blue Child is a relatively recent addition to the night sky? Recent enough that there would be people who refer to it as a new moon?

So let's run with this premise like a streaker who just stole the football in the middle of a game: when did the Blue Child appear? And what. the hell. is it?

We've got enough questions about the White Lady potentially being a goddess. I've suggested in the past that Elune might be some kind of minor Titan, or perhaps an Elder Titan who reverted to a planetoid nature in order to watch over Azeroth - who could be something like a daughter or granddaughter to her.

Could the Blue Child be something like that?

Alternatively, we know that planets coalesce around Titantic world souls - some planets have no Titans within them, such as Draenor, but all Titans seem to start off as these World Soul entities.

But how does that happen? We know that Aman'thul emerged first among the pantheon and then found the others. But where did these World Souls come from?

Also, were there other Titans who were not in the Pantheon? It seems as if only Sargeras was aware of the Titan Argus, and only after he quit the Pantheon did the others discover Azeroth. If Elune is a Titan, perhaps she was simply independent of the Pantheon either voluntarily or because they had never found each other (though the Tears of Elune as a Pillar of Creation and the fact that Eonar hid on Elunaria both suggest to me that they were well aware of each other.)

Azeroth is a future Titan (one who I hope doesn't destroy the planet when she emerges - that's something we really need to get a good answer on. Just give the people of Azeroth some advance warning so they can relocate to some other world before it happens!) But where did the World Soul come from?

If Elune is, in this new conception, some kind of Elder Titan, might she have actually procreated? And if Elune is Azeroth's literal mother, might Elune have other children as well?

Is the Blue Child perhaps, then, just that? A child?
