Highlun is a worked planet for Psi-Wars, a minor fief of a minor Maradonian House, to see just how far a small and measly planet will take you, economically and militarily. The project also might involve space-scotsmen herding space-alpacas.
If you don't know what psi-wars is, the best place to start is probably The Psi Wars Primer. The project is great, and if you haven't read enough of it to get its basics, you should, because its really cool!
