From Guild Wars Wiki
Whitefury Rapids is a special event PvP arena created for the Costume Brawl during Halloween 2007. The appearance of the area is quite similar to that of the Charr Homelands, and to the right of the arena there is a small burned area much like that of Sacnoth Valley. 1 point is awarded for each kill and morale boost, the first party to reach 20 points wins the battle, and each player on the winning team receives a Trick-or-Treat Bag and 7 Gamer Points as a reward.
