The Republic
Ikaanos colony and its orbiting Mastersphere are constituted as a Republic, governed by a Senate who live on the 5,000 capacity space station, and appoint a Mayor to manage the colony on the ground. The Chancellor of the Republic holds the most power in practice however; his title is High Commander of the Mastersphere, and he controls the Ikaanian Marine Corps ("space marines"). The Senate used to be called The Council until Chancellor Mordecai shook things up about 50 years ago in order to cement his power.
