I've been thinking about my bard idea, and Ryan's question about reflavoring gave me an idea.
I'd like to keep the Kalashtar race mechanically - the dual mind, the occasional bouts of madness, etc. but rather than have an entire race of them (unless someone else wants to play one as well) have her be a human touched by a god (Joan of Arc, anyone?). Her visions have led her to believe that she has a divine calling to protect the King and further his interests.
Just to be clear, she'd have all the qualities mechanically of a Kalashtar, and none of a human. The human part would be flavor only.
Does that make sense, and sound like a good start?
EDIT: I'm picturing her being from a different country, BTW, rather than from 'France.' Likely her God has told her that the fate of her country is tied to the fortunes of the King over here. In my mind, the divine inspiration and charisma for the Joan of Arc type play well with both the Bard class and the Prescient build for it.
