Daenerys Targaryen is given three petrified dragon eggs as a gift for her wedding to Khal Drogo by the Magister of Pentos. Illyrio shared that the dragon eggs came from the Shadow Lands beyond Asshai and that the ages has turned them to stone.
Daenerys begins caring for the eggs as they become richer in color. She keeps them in a chest surrounded by candles, day and night as she is drawn to them. Later she earns the name Mother of Dragons.
In this artwork I've created a miniature of the petrified dragons eggs and the chest that they are given to the Khaleesi on her wedding day in Season 1, Episode 1 of HBO show.
