Retrieve Surena's Choker for Gakin the Darkbinder in Stormwind.
I had a student named Surena Caledon. She stood where you stand now, eager to learn of warlock magic, and possessing no small bit of talent. More than that she was young and pleasing to the eye. Had I seen it then, the traitorous trollop!
The thieving wench ran off with a thug, Erlan Drudgemoor. While her loss is of little importance, I gifted her a bloodstone choker that I must have.
Her life means nothing to me now. You will find her at the Brackwell Pumpkin Patch. Retrieve what is mine.
