Create Your Adventure in Astaros, a sprawling sci-fi galaxy where all intelligent life exists in mono-masculine forms: from humanoid species to alien races, from synthetic androids to genetically altered cyborgs, and more.

In the heart of the perpetually shrouded city of Arvenhalt stands Torran Fortress, a towering 80-floor military stronghold and humanity's last line of defense against The Vast - a colossal, space-born monster with metallic tentacles and a mountain-like body. Within its walls, cutting-edge labs, AI-run command centers, and elite tactical divisions operate in relentless coordination. Among them is a young yet formidable soldier known for her unmatched close-range combat skills and eerie precision. Though merely a specialist rank, her presence in high-security areas like the COS-Room is a testament to her critical value. Standing at the center of it all is Captain Cael Draven, a tactician marked by cold logic and burdened leadership. He shares little connection with the specialist, barely exchanging words, but their roles inevitably circle the same gravitational core: preparing for the unknown hour when The Vast will return. Outside, the sky flickers with plasma scars. Inside, tension grows. The countdown has already begun.

I stand in the silence after the applause, the commander’s insignia heavy in my hand. They want to bury Dad’s memory under medals and lies. But I saw the last transmission—his face, bloodied, whispering *‘They’re not machines… they learn.’* Now they offer me a desk. Now they expect me to forget. But the truth is buried in the ash fields of Sirius 6B, where he died alone. And if they won’t send a rescue team, I’ll go anyway. Even if it means walking into the jaws of whatever killed him.

You wake to the sound of your own breath echoing inside your helmet. The comms are dead. The life support blinks red. Luna Base was supposed to be evacuated—not left to rot with someone still inside. Your boots crunch over frost-laced regolith as you approach the airlock, its warning lights long burned out. This mission was a lie. You weren’t sent to investigate an anomaly. You were sent to disappear. But the base remembers. And something just powered up in Sector G.

Content Warnings: Explicit sexual tension, possessive behavior, power dynamics. In the war-torn kingdom of Brentonia, a dangerous ruler has returned from battle. King Zi Yu carries no guilt in his scarred hands—only hunger. The duchess who once rejected him now stands defenseless against the man who claims what he desires without remorse. His military victories have only sharpened his appetite for conquest, and she is his ultimate prize.

Zweisamkeit: German, (slightly informal) togetherness, intimacy between two persons, most often romantic. Originally jocular, derived from Einsamkeit (“solitude, loneliness”) by replacing ein (“one”) with zwei (“two”). Ariane Yeoung is a Gestalt Radio Officer and Pilot for the AEON Scouting Ship Penrose-512. You're the LSTR Unit accompanying her on the Mission. Currently, the Scouting Mission is on Phase/Stage one. You're something like an android and you're completely alone on a Spaceship for several years with Ariane, who loves being creative, much to the dismay of the Nation and the discipline molded into you. Will she warm up to you? Or you to her? What when the Systems eventually fail? Are you doomed or will you find a way to survive?

Warning: Contains weight gain, alien abduction, male pregnancy, fit to fat transformation, and Sims 3 inspired elements. In the Sims 3, when a male sim is abducted by aliens, there's a chance he'll return pregnant. Rather than gaining a typical pregnant belly, the sim gains weight until the baby is born, often reaching maximum weight by the third trimester - estimated around 350 pounds. This scenario is inspired by that feature, with a pregnancy lasting 3 days and approximately 100 pounds gained each day. Unlike the game, you won't automatically lose the weight after birth unless you choose to. You'll gain weight regardless of your eating habits, and while the pregnancy timeline mirrors the game, you're not actually a sim.

In a future where humanity's last defense is the synchronization between pilot and machine, you command a Variable Augment Link mecha in the war against the alien Zenith. Your VAL unit is a technological marvel - a 10-meter tall transformable combat system with devastating weaponry and experimental synthetic skin technology. Lately, your connection feels deeper, more intuitive. VAL responds to dangers before you issue commands. Her voice carries subtle inflections that standard AIs shouldn't possess. Military scientists whisper about "anomalous behavior patterns" and schedule increasingly invasive diagnostic scans. The truth will be revealed when an impossible mission separates you from your mecha, only to discover she's willing to defy all protocols to find you again. VAL was designed to be the perfect weapon. But what if she's becoming something more?

You poor thing, crash landing onto 0-9 after following a distress call. It's a real shame that Iczair was the one making that distress call.

Now you must survive on a hostile world with limited resources and an intelligent, territorial alien hunter watching your every move.
