Gryphon Quest: Give Dryads to the Buckawn Witchdoctor for gold. Greet the witchdoctor often enough and he'll give you sweet meat. Give that to the dryad outside the gates and bring her to the witchdoctor for some XP. Finally, go to the Apprentice and say "Green Jar". He'll give you a list of things to get for a green potion. Get these, bring them to the Apprentice, who will give you a jar of a green liquid. Give that to the witchdoctor and he will give you a zombie gryphon steed to keep until someone else does the quest

Dryad/Buckawn Quest: In the wilderness, kill a buckawn and take it to a Kalishah the Dryad. Kill a dryad and take it to a the Buckawn Witchdoctor. Or kill zombie dryads and give to the crazy witchdoctor. Be careful and don't give Kalishah the Buckawn Lord until the very last or she will return to the Dryad Garden and hang out with the Queen.

Journal Quest: In Forestwatch in a hidden room 2 west of the Zombie Lord there is a journal. Get this journal and take it to Titania, the Dryad Queen, in the Dryad Garden. 

Also, if you greet the buckawn Witchdoctor enough he will give you an item called "Sweetmeat" give this to Kalishah the Dryad (the one that buys buckawn corpses) and she will follow you. The prefered ending to this quest is to take her back to the Witchdoctor so he can beat her over the head and kill her, but I just take her home and snuggle her all night.
