Fortress of Thelvian Tyrkor in Dorsal, Enning
1601
Castle Skaven itself was a formidable concentric structure, layered walls dotted with turrets, offset gatehouses defended by clear fields of fire, traps, murder holes, strategical tricks, the works.
Although not a patch on the fortifications of Thornal (nothing was!), Skaven Castle, like Dun Tolk, was a work of defensive genius. Unlike the other two, as at 2100, it remains.
