Dragons are immense, powerful, winged reptilian creatures, created from proto-dragons by the Titans to safeguard the world of Azeroth millennia ago. They are divided into several types called dragonflights. Since the fall of Deathwing, they have lost their titan-given powers as well as the ability to reproduce. They still remain powerful sorcerers however.[1][2]
The proto-dragons were the ancestors of dragons before they evolved into the sapient, beautiful majestic creatures that they are known as today.[3] Brann Bronzebeard recently uncovered evidence, corroborated by reports from adventurers in Deepholm, that proto-dragons and dragons may have originated from elemental drakes (i.e, stone dragons and storm dragons).[4] Dragons share a common ancestry with both gryphons and wyverns,[5] but it is unknown how far back they diverged.
Galakrond
Galakrond, a massive proto-dragon,[6] is known as the “progenitor of dragonkind.” It is said that it is from Galakrond the titans created the Aspects,[7] but this is a rumor the Aspects actively encouraged so as to keep the truth about Galakrond a secret from the dragonflights.
