The werewolves are part of EQ's yearly Halloween event. They first appeared in 2000 or 2001 if I remember correctly. The first time they did this, there were events in North Ro, West Commonlands, East Karana, The Rathe Mountains, and one other zone, I completely forget because it was so long ago.
The events were made to be done by the level of the people that were supposed to be leveling in the zones. What ended up happening is that the loot that was dropping was so nice for the time, that people were literally having knock-down drag-outs over spawns and selling loot rights for ridiculous sums of money. They did the event the next year and scaled it down to just the werewolves in EC and introduced the skeletons at Butcherblock I think.
Just a bit of Halloween event lore for you. I like this year's event much better than the free for alls they've done in the past. Oh, and for you people who are having a hard time getting pumpkin flesh and/or seeds, get an Unrest mission, the jack-o-lanterns drop them in those as well.
