placement in space: where are the off-world homeworlds?

[Mamorien]

Preliminary math indicates to me that there are probably three orbits between Myrr and the inner limit imposed by e Eri's size, two between Myrr and the asteroid belt that's so close to e Eri b, and two more between e Eri b and the outer asteroid belt. I haven't yet rolled to determine, or arbitrarily decided, what fills those orbits, except that the outer ones are likely to have gas giants.
