The SS Esperanto is a reaserch vessel at the bottom of the ocean on an ocean moon and had developed technology to accelerate evolution. They had managed to generate the equivelent of 35000,000 years of evolution in just 5 years, one of the creatures which evolved was the 'Dispair squid' which wiped out all the other marine life on the planet.

According to the programmer in the Hallucination, they were supposed to use the ships lasers to kill the squid since Esperanto(hope) beats dispair.
