Summary
Over a hundred years in the future humanity has left their home system and joined an interstellar community after discovering the remains of an ancient spacefaring civilisation on Mars. Through the harnessing of element zero and dark energy, and with the technology of the precursors, all advanced civilisations travel the galaxy with the aid of a technology they call … Mass Effect.
Attempting to make her own path away from the one that life set out for her, Lena Kieran Luthor enlists in the Systems Alliance Navy. A few years later, wanting to see more of the galaxy without looking through the bulkhead of a warship, Lena convinces her superiors to send her offworld for additional training at one of the most reputable institutions out there: The University of Argo, on the planet Krypton.

Welcome to the Janus Chronicles. Where we will explore ever possibility that comes with this premise. And if you have any suggestions on what crossover event should happen, or what characters should meet, please let me know, and I will see if I can incorporate your idea into the story.

Summary
You've never been one for deep space. The idea of floating endlessly in the dark, nothing but a suit and a prayer between you and the void, has always made your skin crawl. But when the ship began to fail and the wormhole loomed, you didn’t hesitate—you fixed what no one else could, knowing it meant you wouldn’t make it back.
You expected death. Instead, you were pulled into a part of the universe no one's ever seen. And staring at you from the edge of the stars were two glowing creatures—half celestial, half nightmare—who were far too eager to keep you. Would your crew save you? Or would you find yourself stuck in a place Darker Than Water?

Summary
Her eyes snapped open and she yelped as she saw the grass beneath her. Several feet beneath her. Her stomach lurched as she rose, the air was cold against her back, her heart hammering so fast she could barely breathe. Pebbles drifted upward with her, weightless. ‘No, no, no–’ she gasped, clawing at empty space.
She flails her arms and kicked her legs, begging the invisible force to let her go but she kept going
up,
up,
up.

Summary
Masato applied to the most elite model agency in the galaxy, ECLIPSE- and got in! But what he imagined to be a celebrity paradise turns out to be an automated complex where inhabitants barely cross paths. It's lonely.
Fortunately, the boy in the unit next door to him, Kim Junseo, is more than happy to show him the ropes and make some friendly memories along the way.
Masato's formerly quiet life is shaken up by nosy observation drones, EXP grinding to rank up in the complex's system, and perhaps even a growing affinity towards his new neighbor.
