Lesser Son, Eternal Vengeance

Darius Blackveil was a disappointment. Now, he's a dead man walking. As the fourth son of a noble house, Darius was perfectly content with an abysmal Intelligence stat of 7, a dormant class, and a habit of gambling away his allowance. But when rival House Stormfist slaughters his family at a diplomatic summit and dumps his poisoned body in the monster-infested Whisperveil Wilds, his pathetic run finally comes to an end. Or it should have. His death triggers a three-hundred-year-old bloodline contingency, fusing his soul with Vaelor the Eternal — a sardonic, ancient archmage with zero patience for mediocrity and centuries of scores to settle. Rebuilt from the inside out and armed with forgotten Valorian shadow magic, Darius wakes to a radically altered System interface and one new, un-expiring quest: Blood Debt. Now he shares a skull with the most dangerous mage in history, and Vaelor has opinions about everything. Reborn as the Bloodveil Revenant, Darius gathers a ragtag camp of displaced survivors and begins crossing names off his ledger one by one. But House Stormfist is only the blade. Something older and far darker is holding the hilt — and the conspiracy runs deep enough to shake the System itself. To survive, Darius will have to stop playing the fool and become the monster his enemies thought they buried. For readers who love dark progression fantasy, revenge arcs, and protagonists who earn every inch of their power.
