Ranger Krenn'an, at the Farstrider Enclave in the Ghostlands, wants you to kill 8 Vengeful Apparitions and 8 Ravening Apparitions in the nearby lake.
The lake to the north has been haunted by the ghosts of my ancestors for as long as I can remember, [player]. The poor souls were victims of a tragic incident in which scores of them drowned at the bottom of the lake.
The details of the event are mostly forgotten, but their haunting cries serve as a constant reminder of their curse.
If you're up to the task, I want you to go to the lake and put an end to their suffering, [player]. You will have my gratitude as well as theirs... I'm sure.
