[@BurningCold] I'm gonna say yes on being able to sense when someone else is a chosen. As for a more direct communication, I really can't say because there's a related plot device I don't want to spoil.

[@MegaOscarPwn] I'll take a half-orc, but that's not a role I'm going to give out lightly. Orcs are considered subhuman, and while a half-breed will lack any of the notable deficiencies of full-blood orcs, they still inherit [i]all of the stigma.[/i] The character would be taking flak from absolutely everyone, probably including the party. Its not a role to take on lightly. I think there is a place for someone prepared to play that role but not everyone has the patience and the tolerance to endure particularly harsh in-character bigotry.
