Part of a massive chain from Elder Huo that arguably starts with Earn the Trust, but officially starts with Wraith's Disturbance. The preceding quest is a little confusing, but since you can kill anything in the Swamp and get kill credits, it is unlikely to be so for long. However, The Blood of Wraith that follows has very confusing explanatory text; the target is not named, and contrary to the quest's use of the determining "them", it is a singular creature, namely, the Vicious Devourer, in the Swamp next to the Wraithgate portal.
