The Darker Depths
The Doctored Page
Found in A Brief History of Goblinkind in the East. The Wildfoot Goblin king Krog sought this book after an appearance from his ancestor. After reading the page, Krog decided his people would seek the place they were once driven from.
The place described in the doctored book is a beautiful valley that the Goblins thrived within until the day they were driven out by a horde of orcs. A complex dungeon stands in between this hidden valley and the mountainous regions of East Orus.
