- It would be easy to get lost in the trackless marshes east of Fort Blueblood, on the nebulous border between Blackwood and Argonia. Easy-and probably fatal.
Blackwood Borderlands is an area between Blackwood in Cyrodiil and western Black Marsh. An abandoned Dark Brotherhood sanctuary can be found there, within the ruins of Xith-Izkul. You will travel to Blackwood Borderlands with Green-Venom-Tongue to find out what happened at his old sanctuary.
Kotu Gava and Haj Mota can be found in the exterior swamps, as well as harmless frogs and snakes.
