Dovah (Earth-4552)

Dragons are massive, flying reptiles which can breathe fire onto their enemies, as feared by others as they are admired in Middle-Earth. They are powerful, and intelligent. Their exact origin is debated, though it was clearly stated that they were created by Morgoth in some sense. They were rumored to have a strong connection to magic, later "proven" true when magic begins to return to the world after the birth of the first three in over two hundred years. Dragons possess awesome and terrible power, capable of laying waste to armies and burning entire cities to ashes. Men who were able to tame and ride dragons as beasts of war used them to burn their enemies and forge vast empires across the continent of Middle-Earth.

The last surviving dragons in Arda were possessed by House Targaryen, who used them to conquer and unify the Nine Kingdoms of Middle-Earth one age years before the War of the Six Kings. The Targaryen dragons eventually died out about a century and a half later, however, after which the species was considered to be extinct throughout Arda.

At the same time that the War of the Six Kings began in Middle-Earth, Daenerys Targaryen - last scion of the deposed House Targaryen - miraculously hatched three new dragons from their eggs, and for the first time in generations, filling the skies of the world with the music of dragons once again.
