Empire Outpost
A thousand years ago the empire built a hillfort with an underground storage facility. The Hillfort was abandoned and a small garrison remained, forgotten by the empire. Eventualy they joined local village populations and a tribe of cyclops-orcs occupied the level.

Lost Emperors hidden temple
During a savage succesion war an emperor fled the empire and ocupied the outpost for a time. He dug a deeper palace and temple to live out his days. Better built and more artistic but sealed and forgotten. Devolved Subterranean like Morlocks and troglodytes battle over control of the upper temple and undead occupy the lower level. Emperors brought wealth and magic here which has remained unseen since. Some say his mummy rests here with his concubines and guard. Others say he is sleeping or may be resurrected to rule again.

Hidden Kingdom
This is actually three huge caves. The first is occupied by dark elves, the last by dark dwarves and the middle one is a no mans land with hyena men, bugbears and other monsters constantly battling each other.

Some ancient spirits here have become warped by millennium of darkness and isolation. Some golden servants from the dawn gods or their relics may be found.

Remains of the primordial ones
