Sid Mercer never thought fiction would matter this much.
He was just a 21-year-old guy who loved anime, light novels, mythology, comics, and the occasional physics deep dive at 3 a.m. A walking encyclopedia of fantasy tropes and power systems-great for debates online, not so much for real life.
But when a mysterious system suddenly pulls him into something called the Threadwalker Protocol, all of that useless knowledge becomes his only edge.
Now, Sid is sent to different worlds-each with its own rules, roles, and time-limited challenges. He's randomly assigned an identity every time, and given a trial to complete. In return? A permanent skill or power that evolves with him.
Fail, and he loses progress... or worse.
With only partial versions of each skill to start with, he must adapt fast, think smart, and survive worlds that aren't always fair.
From kingdoms at war to sci-fi dystopias, cursed temples to fractured realities, Sid's only constant is the system and his growing ability to fight back.
Across All Worlds is a multiverse progression story with evolving powers, original worlds, and a protagonist who uses knowledge, creativity, and stubborn will to forge his way through the impossible.
