The School of the Viper had its keep at Gorthur Gvaed, and The Witcher 2 is where the Vipers take center stage. Their most famous member, Letho of Gulet, is the Kingslayer who murders King Foltest at the start of the game.
The Kingslayers
After Nilfgaard destroyed Gorthur Gvaed, Letho struck a deal with Emperor Emhyr: kill the kings of the North, let the sorceresses take the blame, and in return the Vipers would get their school back. Letho did not work alone. His fellow Vipers Serrit and Auckes were part of the plot. Emhyr never kept his side of the deal.
Years before all that, Geralt had saved Letho’s life, and the Vipers later helped Geralt in his pursuit of the Wild Hunt. It is a strange, tangled friendship, and it is a big part of why their final conversation at Loc Muinne works so well.
Vipers in The Witcher 3
If Geralt spared Letho at the end of The Witcher 2, Letho turns up again in Ghosts of the Past, hiding from bounty hunters in Velen. He can even join the defense in The Battle of Kaer Morhen.
