Just talking aloud here.
With due pestering from our caring DM (who agreed that a plain ole' Fighter was boring) I've decided to prestige class Calenthang into the Dark Hunter.
It's a neato Underdark-denizen slayer class (whose accompanying picture of a female dwarf dressed in Valkyrie garb doesn't do it justice) that will come in handy, considering our campaign, and it fits him well enough.
I'll be multi-classing for a level of Ranger to pick up Favored Enemy: Drow and the PrC prerequisite Track.
