Kuruma Seiro was a bastardized replica of the ohitsuji, the Crab ram tower. They were gigantic towers of bone, walking on short, bestial, bone legs rather than wheels. Inside Seiro dangled rotted intestines, waiting to latch onto an enemy fortification. Undead spilled forth from it, eager to attack. Fresh corpses were put inside where they were transformed into Shadowlands foot soldiers. The warriors in the upper part of the siege tower could scout the enemy's defenses.
