The only entrance to the stronghold is a steel gate covered by overgrowth so that only the handle is shown, but even that is concealed by grass and twigs. Its location is 20 feet south of a fallen tree broken in half. It's protected by a strong barrier capable of absorbing 0 tier attacks for a short period which is also linked to an alarm system. The stronghold itself is made of strengthened steel, imbued with energy so that it's not easily or even difficultly destroyed. The facility itself consists of a tunnel from the initial entrance leading down to a branching room with hallways leading to each part of the base. Each hallway is fitted with transparent demon only barriers that require a small amount of time to destroy and are capable of blocking a single strong attack. There are 10 hallways in total, leading to the medical bay, weapon storage, mess-hall, communication, dormitory, transportation, recreation, combat practice, utility, and prison sections of the base. The foliage around the base is made up of trees and bushes, the terrain itself is relatively flat, and there is an underground river that connects with the utility section of the base to provide water.
