“The Alliance has its share of disparity within it as well, and different facets that have bubbled up over the years,” said Danuser. “The Alliance is going to have to realign itself. Especially the Night Elves who lose their home. How are they going to react to this? There’s going to be a real self-examination of what the Alliance is about, and how they want to behave. Do they want to get revenge on the Horde, or do they want to build a better world? That’s a question they need to answer.”
