Cocytus

Cocytus, formerly Axeholm, is a trade fortress in the Underdark. It was constructed in Y897, but was abandoned in Y912 due to constant raids from drow attempting to take the fortress due to its strategic placement. It was reclaimed on Figura 20 Y971 by Hyde Vermillion and Rimuru of Tartarus.

Inhabitants
The fortress is home to many, as Tartarus often invite those they encounter to stay.

All of Tartarus live in Cocytus, as well as those they have invited to move in.

Bilbo was the first to move to Cocytus on Figura 21 Y971, bringing Obby with him as the sewer they has previously lived in was no longer safe, due to attacks by Uthal Keeneye. Cremini and Morel then moved to Cocytus on Figura 23 Y971 after Hyde Vermillion and Rimuru took them on as apprentices. Cassandra Avin moved to the fortress on Figura 24 Y971 after making her way into the Underdark to find Hyde Vermillion. Tharden and Kilia Rockseeker moved to the fortress on Figura 25 Y971 after Tharden helped Balasar Zealous and Steven kill a young white dragon.

Greater Cocytus
Outside of the fortress, Cocytus extends with extra buildings, such as the guard house. There are several small temporary buildings that traders set up, but few permenant establishments.
