In scattered ruins and buried fortresses are murals depicting the same battle. Few have found them of any relevance or import and so time forgot them.
These murals envision stout, hearty… and mechanical warriors, fighting something. These mechanical warriors are called such because in every known instance it is nearly impossible to tell if there is a humanoid beneath the armors. The armor is so intricate and machine-like; it bears locks at every joint and soft-spot.
It is unknown whether these murals were simply works of art or memorials to some long forgotten war.
