The doorway inside the Living Fortress . It is here that the army's weapons became useless to enter this area. No weapons they held even dimensional cannons could blast though these doors. The doors are made of a black metal that has the power to displace force set upon it where it spirals off. Even if it were made of tissue nothing could get through. The Sacred Ancestor was the only one to get through this doorway. Inside here he stayed for a year before coming out, never speaking a word of those events. Rumors and legends began that Six Guardian Knights defended this area, where three of them were beheaded by the Sacred Ancestor, the other were able to wound him before being turned to stone. He then did battle with the Elder God here. A battle that was so fierce, when the Sacred Ancestor finally did leave he slept for a century afterward to regain his strength, and recuperate.
