He opens his eyes to find himself a newborn half-breed bastard in a goblin nest.
Green skin, pointed ears, tusks. Even his own mother calls him a "monster."
He's at the very bottom of the nest's pecking order, liable to be beaten to death, eaten, or disposed of as a "useless half-breed" at any moment.
But he has something no one else does: a Technology Tree System.
Touch some charcoal, and black powder is his. Pick up a piece of flint, and the flintlock is unlocked.
While the goblins are still using clubs to rob merchant caravans, he's already blown up an entire dungeon with gunpowder.
While the knights are still drawing their swords against dragons, he's already figuring out how to make one his mount.
Humans see him as a monster, and monsters see him as an outsider.
He'll use the most primitive technology to blast his way through this world of swords and magic.
The half-breed bastard who crawled out of a dungeon will one day become a being before whom every race bows.
