From introduction:
The star that Aphoom-Zhah was banished to has since been named Gamma Leporis by humans. Aphoom-Zhah and his minions were imprisoned in an alien temple located on a small moon orbiting the fourth planet in the system. Down through the aeons, the alien temple that housed Aphoom-Zhah and his minions was buried beneath the northern polar icecap, and has remained hidden, until now…
Six months ago, a geological survey team was sent to Gamma Leporis by Praxis Mining, to conduct borehole sampling of the various planets and moons orbiting the star. During drilling into the polar icecap on CS402, a moon orbiting Gamma Leporis IV, the mining tractor drilled through the ice and into an alien structure buried underneath.
Upon investigation, the survey team discovered a vast alien temple of unknown origin buried by countless tons of ice and rock. Of course, they had stumbled upon the temple of Aphoom-Zhah.
