Ah. Not from Thedas then. Oh well. It was worth trying and Alistair has no problems with telling others about the Wardens.

With no small amount of pride he explains, "The Wardens are an ancient order dedicated to protecting the world from the darkspawn." A term that won't mean anything if Arya hasn't heard of the Wardens. "They're monsters. Creatures that live underground and try to destroy the surface world. The Wardens are the ones who fight them and keep everyone safe."
