Magic has rules.The world has laws.And the Sea of Rules collects what you owe—eventually.
Charles isn’t a chosen one. He’s an academy nobody with talent that’s almost enough to get him killed slowly.
Then he finds a System Marketplace that sells the things respectable wizards pretend don’t exist: outlaw spells, bloodline upgrades, void-touched relics… and demon contracts—all priced in Soul Credits.
Every purchase makes him stronger.Every purchase also writes a new line into a ledger he can’t erase.
The White Wizards call him a criminal. The demons call him an asset.The Sea of Rules doesn’t care what he’s called—only what he owes.
So Charles does the only rational thing.
He learns to weaponize debt.
