LUX-6: Contact

Lux keeps inventing things or adapting alien tech (ancient tech to the aliens) because the active alien civilizations they discover through portals and probes have gone through cycles of war, decline, and rebirth several times.
Lux further develops the portals using discovered alien tech. Earth empties refugee camps the UN was running (1,200,000) and sends them with a military escort for their "safety." The military sends many ships for escort duty with orders to take over the colony and use the refugees as a labor force. Prissy commands the defense force, and they redirect the refugees to modern housing built rapidly with recovered alien technology.
Other alien groups are contacted, and mixed groups of alien refugees from a war zone are brought back to Green. Alien medical technology was discovered that can expand the human lifespan threefold. Tourists are brought to Green in great numbers to discourage attacks from greedy Earth nations. A demonstration soccer tournament brings in fans and a large number of spies trying to tap into the alien technology. An alien race of Allung (slavers) arrives at Earth and Green. More technology is developed, but each new development adds new complexity to the situation.
The situation gets more complicated until...
