Dragons

Great beasts born of the Magics that made the Universe.  Spawned in the higher planes they burst into the world from the gates.  They almost immediately became crossed with the Giants, and the World shook from their many Wars before time began to be counted.  
Some entered the FEY WILD, brought back Elves and other Fey to assist them in their wars.  Still today the Dragons are the great enemy of most of those of the world.  Their Elf underlings even rebelled against them led by the Elven King of Glamora which led to the Dragon's destruction of Glamora.
Most recently they re-joined with their Elvish underlings and Demonic allies to again try to destroy the PEOPLES OF CHAOS.
