The Witcher from Another World

Oscar Storm is a Witcher from Kaer Morhen, but he is unlike any other Witcher. He maintains his emotions and, though extremely rarely, can still have children.

This made him feel out of place amongst his Witcher brethren. And since humanoids despises Witchers & he kills monsters, he also feels unwelcome in the other worlds.

Then, one day, he accepts a contract to deal with a monster that's been decimating the livestock of a farmer and his family. The Monster reveals itself to be an Archgriffin as Oscar and his horse, Zephyr, pursue the beast upon receiving too many wounds during the fight.

But during the chase, all three weren't looking where they were going and they accidentally ran straight into a portal that takes them to another realm. Once the Griffin have been slain, he decides to explore this strange new world.
