Ten years ago, the USS Eidolon, one of the Federation’s most advanced science vessels, vanished without a trace. Now, a faint distress signal has emerged from the galactic rim—an uncharted expanse of darkness where no stars shine. The signal is unmistakably from the Eidolon, but the ship’s sudden reappearance raises more questions than answers.

The USS Tianlong, a state-of-the-art vessel equipped with experimental Sikkaran technology, is the only ship capable of reaching the coordinates. Led by Captain Reva Sarrik, the Tianlong embarks on a mission to uncover the truth behind the Eidolon’s mysterious disappearance and equally mysterious reappearance so many years later.

What they find defies all expectations: the Eidolon hangs in the void, pristine, untouched by time, eerily silent. No life signs, minimal power, and a fragmented distress signal are all that remain of the once-proud vessel. But the Eidolon is not as empty as she seems. As the away team boards the silent behemoth, they uncover traces of experiments gone horribly awry, and something watching from the shadows of its labyrinthine corridors.

What begins as a rescue mission quickly becomes a fight for survival, as the away team must unravel the Eidolon’s dark mysteries before the ship—and its sinister secrets—consume them all.
