Generations ago, a Goblin clan unearthed what they believed to be an ancient treasure buried beneath their subterranean home. Instead of riches, they discovered a mysterious starship, lying dormant for eons. Now, decades later, burrow-master Daegnon and five unknown stowaways accidentally activate the ship, leaving their mountain behind.

On the same day, Cyrus, an agoraphobic gamer, is encouraged by his counselor to venture outside for the first time in over a year. But his attempt to face the outside world turns into a nightmare when he’s unwittingly abducted by the same alien ship.

Now trapped aboard the ancient Cosmic Sentinel, Daegnon and Cyrus must unite to navigate their strange new reality among the stars. With the help of the ship’s AI, Hoshi, they must attempt to revive its long-forgotten technology and prepare for the challenges and wonders that await them.
