Old Republic mod for Forces of Corruption, the one and only good enough for you.
The blue represents the route used between planets and the circle is to show planets protected by chokepoints. You can only enter the core worlds from Onderon and Fondor. Forces you to hold a whole cluster for better protection and also having more than one way into any cluster making it important to protect your flank and spread your forces.
Special thanks to Niko for allowing use of his GC. It'll speed up the release a lot.
