The ForsakenDefilers seek to foil the League of Arathor in the BattlegroundArathi Basin and claim it for the Horde. The Defilers are an elite group of the Forsaken Military, staged only in the Arathi Highlands. They not only try to secure the Arathi Basin food and supplies for the Forsaken forces, but to weaken the Alliance forces there as well. They seem to show no true loyalty to the Horde forces in Hammerfall, who are more interested in eliminating the Ogre and Witherbark tribes, but to the Forsaken, who wish to destroy the remaining humans in Lordaeron.
Reputation is gained through participation in the Arathi Basin battleground. When you fight in Arathi Basin you earn 10 reputation each 160 resources. On Arathi Basin holiday weekends the required resources is reduced to 150.
