Vratimir is a human-looking half-elven knight with salt-and-pepper hair who befriended Chireadan and Errdil, the latter to the point of helping him renovate his inn in Rinde. Geralt meets the trio outside the gates of Rinde. Dandelion is desperately ill and needs attention, but no one can enter the city after dusk, so the witcher and his sick friend must wait in the barbican along with other travellers waiting to enter.
He featured in the short story "The Last Wish".
