Acherus Deathcharger

So it was probably obvious to a bunch of people who've read all the notes about wotlk how to summon your horsie. I haven't, so it wasn't for me. Judging from the amount of confused people in the start area I wasn't alone =)

Anyways, to summon your deathcharger access your character sheet (by default "C") and check the pet tab. After you've gotten the spell you should have your pony there, ready for summoning.

you hear the Lich King say what a good minion you are and how you have become a good member of the scourge

"Who's my little minion? You are! Yes you are! Coochie coo! Who's a good little Scourge member?"

I hear most death knights are actually hollow, so they tend to be pretty light. Conversely, gnome death knights are filled with lead, just so they don't float away.
