This quest is no longer available in game.
You have been tasked with slaying opposing gnome players in Alterac Valley.
Kill a gnome and return to Ravak Grimtotem at Frostwolf Keep with a Tuft of Gnome Hair.
The Elder Crone has sent me to this warzone to research the other races. More specifically, I am to collect gnome samples. Magatha is primarily interested in their survivability. Aye, the gnomes - while pitifully weak and miniscule - exude great resilience both in and out of combat.
Fortunately for you, I am looking for ruffians to do Magatha's bidding. Return to me with tufts of gnome hair and you shall be known to the tauren as an ally.
