I'm tempted to pick other and choose an NPC like Emma the overly enthusiastic maid from Zeiss who has DEVOURED THE SOULS OF HUNDREDS OF dust bunnies.
But I guess I'll go with Estelle, because shes the leader of the "League of Extraordinary Bracers". --- Trails in the Sky has some of the best writing and most fleshed out world I've seen in a RPG. Now coming to Steam Winter 2013. Sequel confirmed Summer 2014
