“There’s this thing about Anders we were planning… man, I wish I could tell you about it. I won’t, because it’s possible we might resurrect it (perhaps in a different form), but every time it comes up in the Writers Pit we all laugh and laugh and laugh. It’s evil laughter. It feels good. Trust me, you’re probably better off not knowing.”
David Gaider, On Planning Ahead
so basically his life force is supported by the agonized tooth gnashing of bioware fans i guess?
