Final Colonies

Humanity has been driven to a final set of colonies, and war has broken out.   From the original system of Sol, humanity has spread across nearby systems using a system of wormholes. Some of these wormholes travel longer distances across the galaxy, and require more time to pass through, ranging from months to years. Due to this travel time, and the tendency for these "Jump" wormholes to close for short or extended periods of time, former colonies have developed into independent nations. Humanity has now used every wormhole apparently available, and some systems are collapsing.
