Old Map of Enurado

You don't mean to boast, but you're kind of a map expert, and it doesn't take you long to realise that this is a map detailing the depths of Enurado. There are several secret passageways marked on it, as well as what you believe is either a prison or a zombie zoo, judging by the skull and bars symbol next to it. The Alloyance seal is still visible on the map, even though most of it has been scratched off.
