The Oce, an ancient alien species that cling onto a planet and suck the life from it. Once the planet is sucked dry, they move on to the next. Now, the Oce have moved to planet Pel, where a young humanoid boy known as Kaj lives. As the only protectors of their planet, the Galactic Soldiers, retreat, they announce that a select few humanoids are to accompany them to the last standing city where the final ship awaits to take them off the planet. Kaj is lucky enough to be picked to leave his home-world and join the Galactic Soldiers on their shuttle. But, a surprise attack from the Oce leaves Kaj stranded on the surface of his strange world. He must venture through the bizarre biomes of his world and make it to the final ship before it takes off without him.
