Alice and Elias' new home, a spaceship called The Phoenix, has crashed on the Empire's old burial planet, Umbezra. It is a place where only the dead roam. At least, that is what the crew of The Phoenix believe until they receive a distress signal from Alice and Elias' mother. Astonishingly, it seems that she is also on Umbezra. To reach her, the crew descend into the ancient catacombs, where monstrous beings and terrifying discoveries await, all while being hunted by their enemies.
