Dalanoth: The One Book
From D&D Wiki
A comprehensive guide of the world Dalanoth for 4th Edition Dungeons and Dragons
This world came from two minds. It's a world full of fantastic creatures, magic, and adventure, but it started with two kids, a pencil, and a huge stack of papers. Thank you for editing if you wish, but if I catch anyone trying to delete this, there will be blood! Or not, but I do have all this saved in a file... so there's really no reason to. Dalanoth consists of a few separate continents: Orneloth, Topazia, Arcauna, Norvak, and the Underworld (which resides beneath Orneloth). On the other side of Dalanoth are the continents of Herule and Zelector.
Many races cover the lands of Dalanoth, here are a few more common ones.
