George was hired by prefects of Gors Velen who were concerned about the latest ship casualties in Velen near the mysterious lighthouse. When he investigated, he learned that the accidents were caused by local villagers who made fires on cliffs in order to crash and then loot all the arriving ships. After he explained the situation to the prefects he accepted a contract on a Green Dragon that was scorching nearby villages. George left in a hurry and forgot a diagram for his new silver sword that he had to order since his old sword was destroyed.
In the end, the witcher managed to slay the dragon but in doing so was seriously injured. Lying in agony he was robbed of his other diagrams by the locals. He was eventually buried in the Dragonslayer's Grotto in Velen.
- Witcher George is most likely based on Saint George, the Christian martyr who famously slew a dragon in legend.
- There was a painting of him as the Dragonslayer in Kaer Morhen.
