From what I've read as a zealot you wouldn't go around killing people to send to the Raven Queen rather...you'd make sure the spirits that got stuck got...uh unstuck. So you'd be like a shinigami or w/e from bleach...or a ghost buster if you will. Also I think the Bird broad likes gray clothing or something. She's also not a real caring person. So be all zealous about nutrality...if that works I guess.
"...and all the people of the world as one voice sang a hymn.The Song of all creation screamed for justice. We are that justice." -unknown bard's final dictation before the last war.-
