Gaunter O’Dimm

A seemingly harmless vagrant who is in fact Master Mirror, an ancient power that grants wishes and collects souls.

Gaunter O’Dimm looks like nothing special: a bald, friendly vagrant who claims he used to sell mirrors before the war ruined him. In truth he is Master Mirror, the Man of Glass, a being who grants people’s wishes in exchange for their souls and can stop time with a clap of his hands. He never lies and always keeps his word, but his contracts are full of traps and loopholes, and he delights in the suffering of those foolish enough to deal with him. Those who dig into his past believe he has worn many names across thousands of years, and that he is nothing less than evil incarnate.

Gaunter O’Dimm in The Witcher 3
Geralt first meets him at the White Orchard inn in Lilac and Gooseberries. The stranger buys him a drink, points him towards the Nilfgaardian garrison in his search for Yennefer, and asks for nothing, except that one day Geralt might return the favour.

Gaunter O’Dimm in Hearts of Stone
That day comes in Evil’s Soft First Touches. Geralt is locked up on an Ofieri ship, bound for the gallows, when O’Dimm appears and offers to free him. The witcher accepts, a mark burns onto his face, and a storm wrecks the ship. The price: Geralt must act as the go-between who grants the three wishes of Olgierd von Everec. O’Dimm pops up throughout the expansion. In Dead Man’s Party he supplies the blood to summon Vlodimir’s ghost, then cruelly drags the spirit out of Geralt’s body at midnight. At the Alchemy inn he freezes time, warns Geralt that everyone who learned his true name died or met a worse fate, and kills a drunk who interrupts them.

What happens to Gaunter O’Dimm?
In Whatsoever a Man Soweth he comes to collect Olgierd’s soul at the Temple of Lilvani, where a moon mosaic on the floor fulfils the pact’s last condition. If Geralt stands aside, O’Dimm takes the soul, removes the mark and rewards the witcher, even offering advice that can help Ciri. If Geralt wagers both their souls instead, he must solve O’Dimm’s riddle in a twisted otherworld. Finding him in the reflection on water, the one mirror he cannot break, banishes him from this world. He cannot be killed, though, and he warns Geralt he will be back. In Blood and Wine, the curse on Marlene de Trastamara is strongly hinted to be his work.
