Myrkr:

Minban:

All of these would be perfict for the mod as they are planets largly unknown to most StarWars fans and we have a few pictures and comics to go on for the look and style of the planets they each show us.

There is also that cool Reble speeder they show on the one at the top I would love to ride that around!
