The dragoness was introduced in the short story The Bounds of Reason, where she was the main focuss of the hunt.
Not much is known about early life of this dragoness. She was active during the beginning of the 13th century. Around that time, she mated with Villentretenmerth, a golden dragon. After the mating process, he left her for the entire gestation period.
Dragoness begun her search for an optimal place for her nest. She found it in the knigdom of Caingorn. It did not however take a long time and she was noticed by local villagers. They could not accept a dragon in their mist so they decided to hunt it down. Certain individual named Sheepbagger prepared a poisonous mixture of hellebore, belladonna, hemlock, sulfur, pitch and tacks and he stuffed a dead sheep with it. Myrgtabrakke took the bait and devoured the sheep whole in one bite. She then tried to flew off but could not. Instead she fell to the ground barely alive.
Two of the villagers went closer to find out if the dragon is indeed dead. She killed them quicky but she was so weak, that she was only able to lick their blood. After a while, she attempted to fly again but she was simply too weak. Eventually, she limped away, clearly suffering. The locals saw that they managed to gravely wound the lizard yet that was not enough for them as they wanted the dragon dead.
Soon, a whole groop of various hunters assembled to finish the deed and kill the dragon. Among them was the king Niedamir, knight Eyck of Denesle, Boholt and his Crinfrid Reavers, Yarpen Zigrin with his company and later sorceress Yennefer of Vengerberg, witcher Geralt of Rivia, bard Dandelion, sorcerer Dorregaray and last but not least, knight Borch Three Jackdaws with his company of two Zerrikanian women. Each of them had a different reason why to join the hunt and they soon reached the nesting place Myrgtabrakke retreated to.
She would be killed for sure if not for an intervention of her mate, Villentretenmerth, who stood between her, the newly born hatchling and the attackers. The Golden dragon was ultimately victorious and repelled the attacking forces, saving both his mate, and his offspring. After the fight he revealed, tha he and Borch are one and the same. He took the little hatchling and flew off. Myrgtabrakke was left on her own but no longer in any danger.
