The Ballad of the Melting King
A Gigantic tree, one of the biggest in the world lay hollowed out and turned into a massive tower/city. The gargantuan tree has scaffolding build on most of the branches, and big nests which serve as the inhabitants houses.
This place was built thousands of years ago, and has been kept all this time by friendly harpies and bird men.
Ever since the war these harpies have been distant, and do not accept visitors into there home, however they do not resent other people, and have been seen to go out and visit other places in Doldren.
