In 2061, the HLF Corporation was founded with the initial goal of colonizing and mining the nearby moon of Hyperion. Their small mining colony was successfully established in early 2062, within Hyperion's largest crater.
The initial colony seemed unsuccessful, due to a lack of available resources on the moon. The colony was nearing failure, yet was close to cracking through the ice layer. However, all contact was suddenly lost.
Early unclassified reports of recovery teams indicated two things: that a war took place among the colonists, but the sides remain unclear, and something was found beneath the ice layer, although there is no clear information on what it was, the two events are often rumored to be connected.
One of the two sides ended up quickly winning this war before Titan could intervene. Contact was reestablished, but the remaining Hyperion colonists remained very tight-lipped, demanding to speak with only the highest ranking officials of PFS and Titan. They wanted a deal that allowed them to become part of the Republic again, while maintaining sovereign control of the crater.
After a long period of deadlocked negotiations, their request was suddenly granted, but the terms were never disclosed. The HLF Corporation survived the event, and it marked a shift in the colony and corporation from mining to shipbuilding and research, with a focus on combat vessels; following a secondary deal with PFS.
This event became known as the Hyperion incident, and led to further regulations in the protocol for establishing additional colonies, yet the incident itself and the Hyperion Crater remain shrouded in mystery. HLF Corporation allows very few to ever visit the crater, and remains very protective of any intrusion. There is widespread belief that unique resources were what was found buried within the moon, while others point to more extravagant theories, but the truth remains largely unknown.
