Planet of Evolution, a year after the BSL crashed onto the surface of planet SR388 things went from bad to worse as rapid evolution of native species started to evolve into terrifying creatures. The first lifeforms to evolve into a more semi-sentient beings were Kroads and then other mutations occurred on the planet. Then the remains of the BSL were used by the Kroads as building materials for their underground hive-cities and then learned to weld the metal with their own acid.
