At the end of Legion, the Horde and Alliance united and teamed up to take out Sargeras, the fallen Titan, and the guy who — up until now — has served as the probable end-boss of Warcraft. We got on a spaceship and fought a planet, which was weird. Along the way, we learned that some planets — including Azeroth — have souls, and when those souls are born, they turn into Titans.
We stopped the Burning Legion, the game’s main villains since Warcraft 3, and then locked Sargeras up in space jail. He is imprisoned in the Seat of the Pantheon with all of the other Titans, and Illidan Stormrage stayed behind to act as a jailor. This will probably never come up again and we can consider the matter fully resolved.
Azeroth, the planet, and Azeroth, the Titan, both share a name. Because the Titan is sleeping, she can’t communicate much, and when she does, it’s through Magni Bronzebeard, the Speaker of Azeroth. It also means the Battle for Azeroth is a Battle for ... Azeroth. Makes you think, huh?
However, in his desperation, Sargeras stabbed the planet before we could fully lock him up. That sword is still embedded in Silithus, and it is slowly killing Azeroth. Only by sacrificing our powerful Artifact weapons from Legion were players able to slow the damage. It’s an ongoing issue.
Azeroth is now bleeding Azerite, which is popping up everywhere. It’s a powerful alchemy ingredient that can heal, empower, and, most importantly, be weaponized. The logic and capabilities of Azerite are very vague, but it is essentially able to push warfare to a whole new level.
