The Sirbans do not have any defined borders, but they roam the frigid northern sections of Orma.
It is presumed the Sirbans are not yet at the stage in which they have organized leadership.
The origin of the Sirbans is unknown. They have only appeared within the last century or so, and because of their remoteness, it confuses many as to how a whole new group of people could have appeared in Orma.
The Sirbans have not existed long enough to develop historically significant events.
Because of their nomadic lifestyle, it is presumed that the Sirbans are adept at hunting and gathering. It has also been noted that they occasionally ride huge, thunderous beasts called Mammoths.
