lost quest

I couldn't pick up the quest "Where Kings Walk", the last starter death knight quest. The quest stops the people of stormwind from hating you once you hand it in.

You receive this quest from Darion after the battle at Light's Hope Chapel, but he disappeared before I got a chance to pick it up.

My character's name is "Funkykong" on the Lordaeron realm, please let me know if there's anything you can do.

Thanks

Correction, the name of the quest was "Taking Back Acherus" not "Where Kings Walk"
