Barathius is a Legione of the elite Order of ascension, and notably the leader of all the other legiones, making him the leader of both the standard and elite order of ascension. He resides in a room much larger than the other Legione's rooms, in the lower floor of the Monastery of ascension. A Decimation Keystone is required to open the door to his room, in order to kill him once, similar to the other Legiones.
