The Unscheduled Consequence. The Mishaps of Karn, #1

Plans are fragile. Reality is not. Karn Travek was never supposed to exist in this reality. Dragged into a world he barely remembers arriving in, Karn grows up with no family, no clear past, and an unfortunate talent for turning experiments into disasters. After one particularly catastrophic incident involving a university, unstable energy, and entirely too many witnesses, he is exiled to the Rustlands and left to disappear quietly.
Instead, he builds Scrap. Alone among the wreckage of forgotten machines and impossible technology, Karn begins uncovering strange truths about the world, about himself, and about why reality seems to bend whenever he gets involved. The deeper he digs, the more people gather around him: skeptics, strays, survivors, and individuals with extremely questionable judgment. Some of them even become his friends.
Which would be a lot less stressful if Karn did not have a long history of accidentally blowing things up, causing minor catastrophes, and occasionally getting people killed. But as impossible devices awaken and the cracks surrounding Karn grow harder to ignore, the universe itself begins to realize something has gone very wrong. Karn was never meant to be here.
