Driven by hope and a need for answers, he cobbles together a crew of skilled specialists and sets out to unravel the mystery. Their search leads them to Hastur, an otherworldly planetoid where the laws of physics bend in unexpected ways. Upon discovering the wreckage of the Orion, the team is shocked to find Nick's father, Steve Hartnett, alive amidst the ruins.

As they delve deeper into Hastur's secrets, the crew must contend with the planetoid's bizarre and treacherous nature, which seems to defy scientific explanation. Faced with mounting challenges and a growing sense of unease, they must uncover the truth behind the Orion's fate — while seeking a means of escape from Hastur's grasp.
