I might have overlooked a thread. I see tons of info on the Deathknight except what you actually have to do to unlock them? Mainly I am wondering if its a solo quest, group quest, or raid quest? Hopefully its not the latter.
"At this time, the criteria for creating a Death Knight will be the existence of a level 55+ character on the player's account. Once that criteria is met, the player can create one Death Knight per realm."
