D&D's Next Adventure is Baldur's Gate: Descent into Avernus

At the Stream of the Descent (or whatever it's called) Wizards of the Coast has announced its next adventure book, which will be called Descent into Avernus. While the story will start in Baldur's Gate - the Gotham to Waterdeep's Metropolis, sort of - it will quickly send character as low as level 1 into, literally, Hell.

Well, technically the Nine Hells of Baator. But you get it. It's the Outer Plane of Lawful Evil, where players will get way in over their heads in the Blood War - the endless conflict between Devils and Demons, where Law and Chaos clash across the lower planes.

I believe this is the first 5th Edition adventure that takes us to an Outer Plane - Out of the Abyss was filled with demons, but the action took place in the Underdark. Here, however, we'll actually be going to the Hells and fighting (or bargaining) with devils.

Avernus is the first layers of the Hells - built originally as a paradise to lure souls to the Hells, it has become a blasted wasteland and the primary theater of the Blood War. Apparently part of this adventure will allow players to build Mad Max-inspired vehicles from the hellish machinery that the devils use to fight the demons, which suggests the following:

This is the most metal D&D adventure to come out for 5th Edition.

EDIT: As if to seal that deal, Joe Manginello's character, Arkhan the Cruel (the red dragonborn oathbreaker paladin who serves Tiamat) is an NPC in this.

I'm eager to check this one out, even though we haven't even gotten Ghosts of Saltmarsh or the Acquisitions Incorporated book yet. The adventure appears to be built for players of level 1-13 - very intentionally dropping underpowered characters into basically the most dangerous place in the multiverse.
