Dragon egg

Dragon eggs are eggs laid by the Dragon species. They were once highly valuable and plentiful, and were often sold on the black market. Due to the War, Dragons have been hunted to near extinction, causing Dragon eggs to become rare, if they even exist at all.

Uses
As its name suggests, these eggs hatch into a Dragon, the original Firebenders. They are a valuable object; some poachers will go to great lengths to get one and sell it on the Black Market, such as the poachers encountered by Avatar Aang and Kuzon.
