Trolls of a Feather

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.
