Fort Castrum Military Base, Aumesa Captaincy

Fort Castrum Military Base is operated by the Avarian military, located towards the dawnward border of the Aumesa Captaincy. It is part of what is has been nicknamed by those in international intelligence communities the Adamantine Wall of Vacivus. Named for the Vacivus Captaincy which it envelops, Fort Castrum is one of many similar military bases tasked with ensuring the borders of Vacivus are never breached; outsiders are still unsure if they're worried about breaches from the outside or from the inside. Those who work there aren't always sure, either.  

Guarded Garrisons

Those who are stationed at Fort Castrum and other Adamantine Wall bases are not permitted to share details about their experiences there, but some have described it in vague enough terms so as not to risk court-martialing. Some have said it is a cushy, if not somewhat boring posting, while others leave Castrum with thousand yard stares and prayers to never go back.   The Fort itself is quite compact and oblong in shape, its length contributing to the wall which projects from either end. Despite the nickname, the wall is not actually constructed of adamantine. The entire fort encompasses approximately 2000 acres of land.  

Full of Terrors

The Vacivus "Captaincy" which Fort Castrum and the Adamantine wall are said to guard does not exist in any meaningful capacity. The area which it occupies on maps, land which was once part of the Siljak Mountain Range until it was flatted by the twin deities of disaster Katu and Keersik, is devoid of civilization and indeed of most life. Only stumps are left behind of the few trees which grew there, cut down to ensure there is no blockage of sight-lines.   Fey Realm faults, the colorful breaks between the material plane and the Fey Realm that sound the way that honey tastes are common knowledge known the world over. The chittering, gouged out tears between the material plane and whatever hell lies beyond Vacivus are one of the most closely guarded secrets in the world, only truly understood by Avari and some of his closest archons.   Where the Fey Realm has been long entwined with the material plane, two sister planes born of the same waypoint, the realm reachable Vacivus is far older; older than Avari, older than his predecessors, and older than their predecessors before them, given the fact that the land is littered with the remnants of gods that human archaeologists do not remember names for. The scars between planes have allowed the remnants of archons that should have died with their masters to begin leaking out. Attempts at containment have been mostly successful. Only mostly.
