Myrgtabrakke is a green female dragon and Villentretenmerth's mate. In the short story "The Bounds of Reason" in the Sword of Destiny collection by Andrzej Sapkowski, Sheepbagger, a cobbler from Barefield tried to poison her with a spiked sheep carcass, but she managed to get away, though not without suffering some injury.
Later we find that she was in fact pregnant, giving birth shortly thereafter to a baby dragon. Villentretenmerth adopted the baby dragon.
