My pet is almost done. Now I just need something to stuff it with.
Only the voodoo feathers from the trolls in the sunken temple will do. They go by the names Gasher, Mijan, Zolo, Hukku, Zul'Lor, and Loro. Kill them. Kill them all.
This is no trivial task <name>, so I'll make it worth your while by giving you something of Niby's -- he probably doesn't need it anyhow.
Progress
Did you bring the feathers? This doll needs stuffed!
Completion
Wonderful, now my pet is complete!
<Impsy quickly stuffs the doll and gives it a demonic hug.>
Oh, what an odd side effect these voodoo feathers have...
These 6 trolls are the guardians that surround the central area in the Temple of Atal'Hakkar. They are always killed in a normal run of the dungeon.
Prior to Patch 3.0.2, the Abyss Shard summoned a Voidwalker with no mana requirement and with no soul shard reagent. Warlocks interested in high-level raiding and endgame considered the Abyss Shard to be the most desirable of the quest's rewards because of the importance of soul shard management in those settings. Patch 3.0.2 nerfed the Abyss Shard by replacing the soul shard benefit with +sta, so the shard is now considered to have junk status.
