On June 24, 2083 the spaceship Tarquin and its human crew , landed for the first time on the planet Argilus. They found towns and cities, evidence of fascinating alien technology but all was abandoned. There was clear evidence that the inhabitants had only just departed. There were unlocked doors and food at the tables. Strange machinery was still working. But no people anywhere.
After four months the mission supply ship Angel approaches Argilus to make its first follow-up contact. The crew, the two space and xeno specialists Sam Mainey and Hannah Grant can't get any response from the planetary bases. There is no sign of the expedition mother ship.
Sam takes the ship in a much closer orbit where Angel's enhanced com system should be able to raise someone. There is still no response. The com systems seem to be online and operational but no one answers. It is as if the science teams have all vanished. .
They agree to meet at Base 1 and adjust their life-pods accordingly but things they can't control makes them land quite some distance from each other. Their radio links are operational but atmospheric interference makes communication impossible. They set their links on record so that the missing comrade can access it later.
