House of the Dragon: Aegon's Infinite Class Tree

When a game developer from modern-day Earth wakes in the body of Prince Aegon Targaryen, the long-forgotten third son of Baelon the Brave, he expects nothing more than a swift, bloody end in the shadows of his more famous brothers, Viserys and Daemon. But fate has other plans.

Aegon remembers everything: dragons, fire, politics... and the unfinished class tree system he'd been coding at the time of his death. Somehow, it lives within him now, reborn in his soul. Each decision grants him access to traits and abilities no Targaryen has ever wielded; [Pyromancer], [Demon Knight], and secrets yet to be unlocked.

As the Seven Kingdoms groan under the weight of scheming lords, rising dragons, and prophetic whispers of doom, Aegon walks a knife's edge, one foot in prophecy, the other in rebellion against fate itself. With a mind sharpened by two lifetimes and power drawn from beyond the known world, he'll either forge a new destiny for House Targaryen... or burn it all down.
