Introductions and Warnings and Ramblings (oh my!)

Ever since Castiel Milton and his siblings got in a car crash, they've been trapped as spirits in Kansas University, invisible to all but each other.
Castiel is alone and invisible, until he meets Dean, and they form a sort of unusual friendship, which spirals into something much more.
