Outworld Rim
The outermost region of the Mizar System, containing the stars Mazir, Phokus, and seven planets and their respective moons. Portions of the Poneeian Asteroid Belt are sometimes considered as part of the Rim, but this is usually due to local orbits.
The overall size of the Rim covers a roughly 4.5 billion kilometer wide ring beyond the Poneeian Asteroid Belt.
My brain can't comprehend 4.5 billion km. Wow. This is why space is scary. I look forward to knowing more about the planets of the Outworld Rim! :D
