Mirror Man - The Witcher 3 3D model

Not much is known about Gaunter before his meeting with Geralt, but he stated that he was a former mirror merchant-turned-mangy vagrant because of the war.[1]

Meeting in the White Orchard innIn May 1272, Gaunter O'Dimm visited the inn of White Orchard, and was approached by the witcher Geralt, who was searching for Yennefer. O'Dimm asked to buy the witcher a drink, and that he knew about Geralt and Yennefer based off Dandelion's ballads.

Pushing for an answer, Geralt continued asking whether he had seen Yennefer, so O'Dimm told him local rumors he had heard and advised him to go to the nearby Nilfgaardian Garrison to continue his search. He remarked that he didn't need a reward as one day he may need Geralt's help and then suddenly disappeared.[1]
