From the file's introduction
From radiation and black holes to meteorites and cosmic rays, the threats of the cosmos easily trump those of even the harshest terrestrial wilderness. Two derelict spacecraft orbiting a planet on the fringe of known space pay silent homage to the fragility of human life and the raw, devastating power of space. For the past two years, the I.S.S. Beagle and End’s Run have orbited this planet, locked together in a grim dance of death. Can the heroes unlock the secret of their destruction without falling victim to the same fate?
A short d20 Future adventure for four 5th-level characters.
