Treebole wanders around this area, turn into him.
This is kind of a long one. First, you need to kill Dire Ravens until you get 5 Dire Pinfeathers. Then you need to go into Grisnath and get Grisnath orbs. When you combine one feather with one orb, you get an Exorcism feather. Then, you go to find Leafybeard trees(not the stronger stonebark ones) and use the exorcism feathers on them, then kill the koi-koi spirit that pops out.
Once it's done, turn it in to Treebole.
Maxnar spawns in the cave at this location, if you're lucky you can get all the way tothe dragonkin in costume form.
HE's a tough fight, but definitely soloable. Turn in all quests after this.
