Yuris Clayve was supposed to be worthless.Branded with the lowest civic class, Scavenger, and cast out by the Royal Artificers' Guild, Yuris is left with nothing but his late father's old tools, a sick sister to protect, and a talent no one in the capital understands.But discarded magical tools are not truly dead.Broken lamps remember how to warn.Cracked purifiers remember how to let people breathe.Failed barriers remember who they were meant to protect.And beneath the capital lies an ancient ash-furnace system built from the memories of everything the city threw away.When the poisoned lower ward of Grayrain begins to collapse under hidden magical waste, Yuris discovers his true power: reading the final functions of broken artifacts and rebuilding them into something new.With scrap metal, rejected cores, ruined records, and the help of unlikely allies, he must uncover the truth behind the buried Starwreck Labyrinth, expose the corruption of the guild that exiled him, and create the impossible:the Gate-Lock Furnace, a city-scale magical device built entirely from discarded things.But the deeper Yuris reads, the more he realizes the city's greatest danger is not the trash it threw away.It is the belief that anything, or anyone, can be declared worthless.A slow-burn underdog fantasy about reincarnation, magical crafting, found family, broken tools, hidden corruption, and a discarded ward that learns to shine like a sky full of stars.
