Eric and Hunter return to the world of The Witcher. They're a little bit rusty, but the swords are sharp as ever and a couple potions in their glasses get them through.
Note: Geralt is in fact 90-100 years old during the events of the Witcher III (according to a lore entry in the game), but Sapkowski never actually states his age.
