Dragons

Dragons are magical creatures, only recently returned myth and legend. Daenerys Stormborn, of House Targaryen, hatched three living creatures from eggs of stone, ushering in a new age of magic and dragonfire. These three dragons - Drogon, Viserion, and Rhaegal - would go on to have progeny of their own, leading to the resurgence of House Targaryen's arsenal.



Characteristics
Much and more has been written about dragons and their nature. Those details so steeped in the arcane can be found here.

Ancient and Legendary Dragons

 * Urrax was a legendary dragon slain by Serwyn of the Mirror Shield in song. Many claim now that he was a member of the Kingsguard, though that organization did not form until thousands of years after Urrax was supposedly slain.


 * Terrax was the dragon of Jaenara Belaerys, who flew to Sothoryos and explored further than any before her.

The names, stories, achievements and riders of the original Targaryen dragons can be found here. Though eggs from this era yet remain, most have been lost or prove dormant.

Known Dragons and Their Riders
''“We shall not pretend to any understanding of the bond between dragon and dragonrider; wiser heads have pondered that mystery for centuries. We do know however, that dragons are not horses, to be ridden by any man who throws a saddle on their back.”  –  Archmaester Gyldayn''  '

Known Dragon Eggs
''“Someday the dragons will return. My brother Daeron’s dreamed of it, and King Aerys read it in a prophecy. Maybe it will be my egg that hatches. That would be splendid.” – Egg ''
 * Prince Maelor’s Egg:  An egg that was white with swathes of green borne of Viserion.  Never hatched. Entombed with Prince Maelor upon Queen Olenna’s instruction.
 * Seastar’s clutch:  Seastar has, to anyone’s knowledge, lain only three eggs.  One of which was hatched, and the others that are stored in the Red Keep by royal decree.
 * Silverwing’s cache:  Of these eggs, Grand Maester Selwyn has deemed only two to remain viable. They are stored in the Red Keep.
