Boundary Ruins

Cole Rayner, a 34-year-old architect from Chicago, had his soul intercepted by an ancient distress signal after death, plunging him into the "Boundary Ruins"—the sedimentary layers of failed universes. This isn't hell; it's a junkyard. Nine universes collapsed, their wreckage stacking into a nine-layered abyss, and he is the first living soul to ever step inside.The Boundary Ruins operate on a set of cold, unyielding physical laws. Periodically, an "Entropy Tide"—a darkness with actual weight—submerges everything. Here, any unsealed crack is an open door to oblivion, capable of draining your very existence into nothingness. Gray moss is the only food; it replenishes not calories, but the "existence" scraped away by the tide. The ring serves as an anchor, the slate as a guide—yet the slate never tells you how to survive directly. It only casts out a single word when you are on the verge of death. Whether you can decipher it depends entirely on what knowledge your mind holds.Cole can only solve these deadly puzzles the way an architect would. He builds stone huts—not to shelter from the rain, but to block out entropy. The Law of Zero Gaps dictates that the sealed perimeter of an anchored zone must be continuous; a single centimeter break means death. Six Guardian Altars block the entrance to the abyss, each gate demanding a specific sacrifice—not livestock, but a part of yourself. The Tooth Pillar doesn't want a tooth; it demands a pile tip. It's the urban planner's first lesson: a skyscraper stands tall only because of the first pile driven deep into the earth.Cole is the only human in the Boundary Ruins. No companions, no dialogue, no narration. He carves blueprints into his forearms, treats the Entropy Tide like a construction site inspection, and views every near-death experience as a test report. Every time he nearly dies, he learns a new rule of this broken world.Descend. The source of the signal lies in the deepest depths.
