The universe of Diablo has a surprisingly rich backstory, and on the first day of BlizzCon, some of the writing team for the new Reaper of Souls expansion sat down on the panel stage to answer attendee questions. Many of the questions dealt with those little minutae and side characters of the world lore nerds (such as myself) love so much, but there were also fun and interesting insights into Reaper of Souls and future stories in the Diablo world.
Q: Could we have a failure cinematic if we die to Malthael?
It would be too expensive and time consuming, and would require dropping other features. That said, the team is considering special events if you die or fail, but can't promise or reveal anything on that front yet.
Q: While Bul'kathos appears to be the main Barbarian hero, the Immortal King set refers to someone called Worusk. Who is the true supreme Barbarian and who is Worusk?
