What it is
The Broken Isles are the center of Legion's invasion, but the expansion's real structure is collaboration. Class orders, faction leaders and old enemies have to act across former boundaries because the Legion is attacking Azeroth itself.
Illidan's return belongs here because his story stops being only the tale of Outland. The war reframes what he was preparing for, while the world pays the cost of finally confronting the Legion at full scale.
Legion brings old narrative debts together: the return of Illidan, the demon hunters, the class orders and the question of whether Azeroth can cooperate without dissolving faction identity. The victory matters because it is built through institutions that did not exist at the start of the war.
The short version
- The Legion's invasion turns individual class stories into a shared defense of Azeroth.
- Illidan's role is recontextualized after Outland.
- The war leaves a wound in Azeroth that drives the next era.
- The Broken Isles make cooperation a practical structure through class orders, not merely a plea for temporary unity.
