I don't know, many of the companions embody superpowers. Varric=stone=lyrium (dwarf deity) isn't a stretch at all. I'm still trying to figure out who's Dorian, unless he's the dragon instead of Bull.
This works with a model I'm trying out, with each companion representing a virtue. There should be a representative from each, and I've got Varric/magic (dwarves can't practice it because they are it), Solas/harmony, Cassandra/faith, Cole/compassion, Dorian/pride (but not the demon kind), Blackwall/valor, Vivenne/ambition, Sera/equality, and Bull/discipline. My labels are pretty arbitrary, and far from perfect. It's a work in progress, really just a wispy concept that creeps in as I'm playing, but hey, fun to think about.
