A Witcher In Westeros

This is a story where Geralt of Rivia had an apprentice named Eragon, he was riding with Geralt and Yennefer to the tower where Avallac'h took Ciri after defeating the Wild Hunt. Eragon accidentally rode through a portal that took him to another land known as Westeros. Eragon's presence will change the course of history.

I do not own these characters, only my OC's. Heavy AU of Game of Thrones.
