Needless to say that some DA players weren't pleased to hear this. ;')He was however incredibly forthcoming on the Fluff side of things, as I had about 15 minutes with him talking about one of (and his) favourite characters: Cypher.
Jervis revealed (and I can quote him on this) that Cypher is "absolutely NOT a Chaos Space Marine". The way he envisioned Cypher is as an avatar of redemption, that in some sense the fallen Dark Angels are the good guys, as they see their mistakes and learned from it, but the Dark Angels simply can't see past it, and instead decide to kill things to solve the problem. He also said that Cypher is not entirely human (or super human as the case may be) anymore due to the rend in reality that shattered Caliban, casting the fallen angels through space and time. He said there's a mystical aspect to his character. He also explained a lot of where he got the idea from, a Clint Eastwood movie called High Plains Drifter was his main inspiration.
