Centuries before the Clone Wars or the Empire, in the early days of the High Republic, it was an age of exploration in a galaxy far, far away. . . .

It is a time of excitement and discovery. Daring pilots chart new routes through hyperspace, while Pathfinder teams make contact with frontier worlds to invite them to join the Republic. When a Pathfinder team’s communications droid is found drifting in space, damaged and bearing a cryptic message, Jedi Knight Silandra Sho and her Padawan, Rooper Nitani, are sent to find the missing team members. Their investigation leads them to the planet Gloam, a ravaged world said to be haunted by mythical monsters. But the situation on Gloam is more complicated and perilous than they know. A hyperspace explorer named Spence and his son, Dass, are stranded on the planet and have learned that the “mythical” monsters are very real and very, very dangerous. Spence manages to activate a distress beacon to call for help but fears their time is running out as the monsters close in.

Can the Jedi find the missing Pathfinders, save Dass and Spence, and unravel the mystery of the monsters? The answers lie in a hidden city beneath the planet’s surface. . . .
