'Exodus: The Helium Sea' author Peter F. Hamilton talks universe crafting and finishing the story in this second prequel novel for sci-fi RPG 'Exodus' (exclusive) At some point next year, when planets and stars momentarily align, we’ll hopefully be getting what’s sure to be the most anticipated sci-fi RPG in recent memory — Wizards of the Coast and Archetype Entertainment's "Exodus", which is coming to PS5, Xbox Series X/S, and PC. This far future "Mass Effect"-like saga follows the daring time-traveler Jun Aslan as he and his companions hop about the cosmos searching for ancient artifacts to ward off the destruction of their worlds. This threat comes from an evolved group of transhumans called Celestials, with the whole affair taking place within the Centauri Cluster, 16,000 light-years from an abandoned planet Earth. As part of Archetype’s ambitious cross-media marketing plan, the dev team enlisted the help of celebrated British sci-fi author Peter Hamilton ("The Salvation Sequence") to fortify the game’s worldbuilding and also pen two companion prequel novels. The first of these books, "Exodus: The Archimedes Engine," was released on Sept. 17, 2024. Now, the second half of this duology, "Exodus: The Helium Sea," was just published on June 16, 2026, and continues the tale of Finn and his human allies to see if they can outwit the Celestials and finally earn their fellow humans a place of independence and power in the Crown Dominion. The epic conclusion of the Archimedes Engine duology by legendary author Peter F. Hamilton. Set in the universe of EXODUS, a new sci-fi action-adventure RPG coming soon from Archetype Entertainment. "Because I helped build the 'Exodus' world, they sent me what I always call the skeleton, and I helped put a lot of flesh on it, like the assorted cultures, some of the technologies, and the starships," Hamilton tells Space. "It was partially my universe to write in, so I knew the limits and constraints, which made it easier because I was part of the structure." "The Helium Sea" concludes the background saga started in "The Archimedes Engine" and is one story told over the course of two books. "All the characters that were alive and survived at the end of 'The Archimedes Engine' just carry on into 'The Helium Sea,'” he adds. "You get to find out what’s been hinted at before and what the real motivations are for the rebels and who they are. It was all misdirection; some people we think are on the bad side are not, and you get to see a whole lot of new places and settings as well, and it really expands the universe." "The last one was set over 40 years because we have a lot of time dilation elements when you travel at relativistic speed," explains Hamilton. "This book is set over ten years, and you have various characters going on different missions, and I had to bring them all together at the same time and same place. That was a lot of plotting." Hamilton admits that his collaboration with the whole Archetype team on the colossal "Exodus" project has been an enriching affair. "The joy of it was, which I’ve never had before writing a book, is that I'd send them a description of a world or something, and I’d get my little spaceship back, and it would be this magnificent picture, and of course, being top-flight artists, they've added to my original concept. It was a real growth process, developing this world. We all got on really well, and we just gelled. They were very professional. You could see they had a job to do and they were doing it." When pushed to choose a favorite destination amid both "Exodus" prequel books, Hamilton immediately picks a world called Kingsnest. "It's a glass shell, a glass bauble, the size of Jupiter basically, which has been pumped full of atmosphere," he notes. "The ships they have in it are made out of wood, sort of 18th-century sailing technology, because there are clouds in there and little globular lakes. So much life in there. It would take you more than a lifetime to sail across it and encounter who knows what in the deeps of it. I just love the idea of it. That you can literally have sailing ships in space." Now enjoy this exclusive chapter excerpt from Peter F. Hamilton's "Exodus: The Helium Sea" (Random House Worlds) The Jiyoratan family had furnished their tower with stylish opulence. No sign remained visible that the structure was aerolite; every wall was tiled. The aesthetic was clean, with geometric primary colors starting to warp together within soaring arches that highlighted the central atrium, where a lush hanging garden claimed the walls. Internal balconies were illuminated by faint blue lights in constellation displays, half-hidden among the foliage to create an illusion of the external edifice of some tropical villa. Spiral water features ran the full height, bringing a humidity to the scene that Neusch had practically forgotten. His clothes activated, changing to a light layer of armor around his body and limbs, while the hood slipped over his head and curtained his face in a transparent shield. He’d never envisaged the bio-andy being involved in anything as crude as an actual fight, so he had no idea how much use the protective clothing was going to be against the Guillrameo team. Probably not much. Until now he’d only had a vague plan: get to the sisters and get them out. Quietly. The kind of mission his father would’ve executed superbly, where no one would even know he’d been there until hours after the event. Well, that’s just taken a deep dive into a sea of shit. The other Guillrameo operatives were efficiently eliminating the aireels he’d sent after them. Within thirty seconds they’d all been taken out. He didn’t know where the woman was—presumably making her way through the Dibyth tower to the first target. The others would be breaking through the walls any minute now. The bio-andy picked up voices somewhere inside the atrium. He started running for one of the curving granite stairs that wound up between the atrium balconies. The sisters had their quarters two floors above, along with the rest of the family’s youngsters. Three people came around the central trio of big fountains, stopped in surprise. One of them who’d worked with Juliatra-Monoth gave him a startled look. “Halvin-Aneil?” “Sound the alarm,” he shouted at her. “People have entered your home. They’re going to kill most of you and interrogate the surviving seniors.” “Huh—” One of her companions, a man, made a grab for the bio-andy. It pushed back hard, sending him spinning. “Sorry! They’ll be armed. Get out of here.” Then he was around the fountains and heading for the base of the spiral staircase; people were walking down it. His lnc warned him an intruder alert had been issued within the tower. That’ll annoy the Guillrameo team. “The Dibyth has been isolated from Husnak’s network,” the CI informed him. “No security forces know what’s going on.” So, no help’s coming, then. Neusch barged past the couple on the stairs and released a flock of insect drones from his leg pouch. They zoomed up the inside of the atrium, heading for the balcony above, hunting the girls. Andys started to emerge from every doorway. Even without weapons, the slim silver figures would pose a problem. But that suddenly didn’t matter. The tower network vanished. The andys lost all rigidity, fluttering to the ground like becalmed flags. “Asteria’s arse.” Neusch drew the bio-andy’s guns—an enhanced-projectile mag carbine and a gamma laser. The bio-andy reached the top of the stairs, and Neusch cursed the way the verdant plants had been allowed to flourish, narrowing the balcony. Tactical display reported a scan locking onto the bio-andy. Neusch relinquished fire control to the bio-andy’s tactical routines. It raised both guns and assumed a crouched pose as it started to sprint along the narrow route. A projectile hit the side of the balcony half a meter behind it. The bio-andy was flung off its feet, the light armor turning rigid. It landed, crashing into a big night-flowering jasmine bush, rolling with gymnastic precision, firing a burst of gamma rays at the origin of the attack on the floor of the atrium, then sprinted onward. Neusch split his consciousness. One was with the bio-andy, observing and providing oversight guidance. The parallel Neusch was searching the home’s blueprints, combining with the CI to find an escape route for the sisters. First realization, as another barrage of projectiles slammed into the balcony behind the bio-andy: this was going to require maximum firepower, because the Guillrameos would unleash nothing less. An X-ray laser slashed across the bio-andy. Its light armor managed to diffuse and deflect most of the energy so that it broiled the balcony’s surrounding vegetation. Leaves and twigs fried, bursting into swirls of ash and embers around him. Neusch was acutely aware of nerve-equivalent impulses reporting the beam penetrating the light armor, searing the bio-andy’s hip and thigh. Muscle damage parameters were incorporated into the body’s physiology routines; it changed its posture slightly to accommodate the now asymmetric strength of its leg muscles. Three mouse-sized drop-drones flipped out of a leg pouch; they had a similar leg structure to the cutter-drone, but they were combat versions. The trio lunged over the balcony rail in full lemming mode. One released a chaff cascade—hell’s own monsoon manifesting as specks of light, sound, and EM pulses falling through the hanging garden. The other two went dark as they fell, unnoticed among the sensory overload. They hit the floor and did nothing. A few seconds later, as the chaff attack faded, two of the Guillrameo operatives crept into the atrium, their protective cloaks lensing the light around them: event horizons made from fabric. Their movements created subtle motions in the air that the drop-drones identified. The bio-andy had just reached the archway leading to the children’s bedrooms when the drop-drones detonated their proton-boosted explosive cores, eradicating the two intruders. A massive blastwave punched the bio-andy through the air, sending it crashing hard into a wall. This time, it took longer to get to its feet and totter forward. One hand slid along the wall for additional balance as it reached the door to the sisters’ bedroom. Which had been locked by the emergency intruder alert. For fuck’s sake, I’m trying to save you! Another cutter-drone let go of the bio-andy’s belt where it’d been clinging and hurried over to the door. Its proton incisor deployed, and it climbed up the edge of the door, slicing through the rim as it went. Neusch sent six more drop-drones flipping away. They sped back down the corridor, taking up positions at three-meter intervals. Neusch saw a couple of the house’s fire-andys roll along the balcony, their extinguisher nozzles deployed over the railings, pumping clouds of viscous yellow retardant foam into the atrium. The part of his consciousness focusing on tactics directed two of the drop-drones into the blobs of foam that fizzed away on the balcony floor. He then dispatched a dozen more insect drones—not confident they’d be any use, but he needed some visuals on the remaining Guillrameo team even if they only lasted a second. The cutter-drone finished its work. With a swift prayer to the Goddess that a kick would be enough, he raised the bio-andy’s good leg and booted the door. It flew open to a scene of fear and chaos. Five children in their nightclothes were clinging together in defiance, struggling not to scream and cry. He identified Kimiya and Marize, hugging their spawn brothers as they glared fearfully at him. “It’s okay,” Neusch assured them, raising the bio-andy’s arms. Probably not the best gesture given it was still holding a gun in each hand. “I’m here to stop the attack.” Again, not helpful. His last three cutter-drones raced past the frightened spawn siblings to the wall. The tactical display told him two weapon-drones were rising up the center of the atrium—hand-sized silver discs, moving fast. They took out his watching insect drones. The tactical display fell back on the drop-drones for information. The first of the weapon-drones came up level with the second floor. It darted forward. Neusch detonated the two drop-drones on the balcony. They must have triggered whatever explosives were in the weapon-drone, and the resulting explosion sent him reeling. The children screamed as they were slammed to the ground. The air in the bedroom instantly became a blizzard of trash. Two drop-drones in the corridor outside survived. They righted themselves and scanned around. The tiles and artwork on the walls were smashed and smoldering, chunks still peeling away from the thankfully stubborn aerolite. The bio-andy scrambled to its feet, its medical display showing several damaged areas, but it remained capable of locomotion. Neusch knew he only had seconds before the Guillrameo team hit him with something else. Kimiya was closest, sprawled across the floor weeping, debris swirling around her. He snatched her up and held her tight against his chest. She screamed in dread. “I’m sorry, but it will be okay. You’ll see. I promise.” She struggled. It was pointless, of course. Even if it’d been a real adult Imperial Celestial gripping her, she wouldn’t have been able to break free—and the bio-andy was considerably stronger. The three cutter-drones finished slicing the bedroom’s window out of the wall. It fell soundlessly into the night beyond. “No!” Kimiya wailed as the bio-andy moved toward the gaping hole. “No, no!” Her voice became a wordless shriek. Her spawn siblings cried out as she was carried past them. “Follow me,” the bio-andy shouted at them. “It’s the only way you’ll live.” He reached the window and jumped.
