Founder's Mesa

As the Vertansion Empire cemented its control of the world, they established shrines and other strange constructs to service them. One of these facilities saw them hollow out an entire mesa though the empire fell before its true purpose could be revealed. In the ensuing decades the mesa was settled by Dragoons, notably the Alpha Clan. 
As time wore on they built up the mesa, converting it into a massive military headquarters. Dubbed Founder’s Mesa by Chieftain Charles Bloomer I, it would soon become an unflinching symbol of the Alpha Clan’s power and dominance.
Taller than anything else for miles around, visitors cannot help but have their eyes drawn to it. But despite the natural beauty of the formation it is now a seething mass of automated defenses and checkpoints, a pure bastion of Dragoon might.
