Sanghor: Kingdom of Blood
Known as the Kingdom of Blood, the goblin nation of Sanghor has been destroyed and reborn countless times. Today Sanghor is little more than a scattering of rocky islands hewn into hideous fortresses. The goblins that infest these evil bastions worship Tiamat, and each tribe is ruled by a wyrmlord (usually either a hobgoblin or bugbear warlord). From time to time, a particularly powerful wyrmlord rises to unite the goblin tribes under a single banner with one purpose in mind: to slay the Dark Queen’s enemies and harvest their blood.
The goblins of Sanghor frequently ride dragons into battle. Tribal warpriests tend to the dragon hatcheries and raise the newly hatched wyrmlings so that they’re willing and eager to serve as mounts. These goblin warpriests feed the dragons a steady diet of meat and blood so that they remain devoted to the tribe and their Dark Queen.
Sanghor is also home to evil dragonborn who follow the teachings of Tiamat. Most of these dragonborn are Dragovar agents who seek to rekindle the glory of the ancient dynasties by enslaving all non-dragonborn races and seizing their lands.
