For those who haven't mucked around with the Draenei yet, that's the racial healing spell you get. One of the first baby quests you get is to use it to revive someone hurt really bad (bodies are everywhere). I sent a night elf rogue to the Draenei starter area and guess what? Apparently anyone can get the Gift of the Naaru quest. I'll have to send a healer in to see if they can actually complete it (my rogue didn't even have bandaids).
