From Skavenblight a deep trench has been dredged, reaching through the blighted marshes and emerging on the coast of the Tilean Sea. The ramshackle vessels of the Skaven fleet tirelessly trek up and down this dismal waterway, on unfathomable errands for the Skaven Warlords who dwell deep within Skavenblight.[1a] A Skaven Clanfleet typically consists of many small fireships scurrying around the Great Bell of Doom sitting at the centre of the fleet. Clan Pestilens Deathburners watch for opportunities created by the Warp-raiders, waiting for crippled ships to pick off and destroy.[1a]
