Do they ever elaborate as to the conflict between the Writers and the Painters in 'real-world' Lumiere? I thought there would be some elaboration as to that and how that led to the fire...unless I just missed it.
Given that Verso doesn't like being a Painter I also wondered about Musicians, would they be a third artist group?
(The getting lost in worlds you create that are better than real life is a serious deep cut at the whole gaming industry)
