My Ego is Harder Than My Steel

Kasimir Lenz remembers the end of the world. He remembers the 'heroes' of the Azure Comets guild - powerful, celebrated, and utterly incompetent - failing to stop the Calamity. Now, sent back in time to the body of the guild's underappreciated blacksmith, he has one mission: prevent the apocalypse. The only tools at his disposal are his forge, his encyclopedic knowledge of monster weaknesses from his past life, and a guild full of reckless glory-hounds who think his meticulously crafted, sentient weapons are just shiny toys. Kasimir must secretly embed life-saving strategies into every piece of gear, manipulating the Comets from the shadows just to keep them alive. But his cold, logical approach clashes with the guild's chaotic energy, especially with their fiery leader, Anya, who is as frustratingly perceptive as she is impulsive. As he works against a catastrophic deadline only he knows about, Kasimir discovers his soul is literally bound to the guild's fate - if they die, he fades from existence. Can a man who sees people as pawns learn to forge a real team before they all get wiped from the timeline?
