During 450, the Tal'mahe' Ra split into two separate branches in a secret war that was mainly fought within the Underworld. Some claim that the war was instigated by the Inconnu or the wraiths. The two groups developed different styles, the eastern branch was influenced by the Euthanatos and the traditions of the native Assamites and Setites, while the western branch was interwined with the Verbena and focused more and more on mortal politics.
