This dragon made her nest in a high mountain located in the Fire Nation, and laid an egg. The location of the nest was mapped out by a cartographer and sold at a cheap price. One of these maps fell into the hands of poachers, while another fell into the hands of Kuzon and his friend, Aang.
Some time after this, her egg was threatened when the poachers distracted her. One of the poachers lured her out of her cave, allowing the others to grab her unborn offspring. However, Aang and Kuzon stumbled upon the poachers, and, using Kuzon's firebending abilities, tricked the poachers into thinking she had returned. They ran off, but her egg was nearly smashed when she returned and knocked it out of Aang's hands, incorrectly assuming they wanted to steal her egg.
Aang managed to catch the egg just before it hit the ground, convincing the mother dragon that they were no threat to her or her offspring. She was grateful, but refused to take them for a ride as Kuzon had hoped.
