[KoH] Mastodon Castle, Durkar Plains (WIP-90%)

This fortress was originally a small single-layered castle atop a hill, but as time went by it was upgraded and fortified to an extensive level, in response to the large numbers of raiders and siegists crossing the planes from the northern sea front. Due to the long, steep slopes, the castle is almost completely immune to siege towers and battering rams, and the layout is specifically designed to force attacking infantry through bottlenecks where archers can easily pick them off from the walls.
