Few creature know of this form of dragons, of those, fewer still know how such an abomination could have been created. Some believe these are the soul of evil dragon reborn to suffer, other believe they are the result of a mad wizard experiment...none know and few care when these creature die off

The Fire Blooded Dragon very blood is that of molten lava. their scales are blue but as their blood burn, the scales darken to black from the soot. It such an awesome and frighten creature to behold, even among most dragons, that the dark truth behind them is often over look...
These dragon do not have a resistants or an immunity to the fire and heat. From birth to death, they stay in a constants state of burning from the inside out. the only immunity they have is to water and ice, making using such attack impossible to hurt them...and sadly, given them no relief from their burning existence by diving into water. There is no getting use to this, each pump of their heart is a fresh new sheering pain reviving in their core, the few capable of passing out asleep despite the pain some time die choking on their own smoke given off their body.
Living in such a life of pain, it no wonder these Dragon are aggressive and in a constants state of rage and pain which they unleash in a soul shattering roar. Because they have no tongue, and because everything they eat burn into charcoals, these creature eat everything, not caring what so long as they can eat, anything....
Long ago, some of these Dragons souls was capture in blades called the Fire Blooded Saber, but over the countless century it was merely called the Dragon Saber. When the full power of this otherwise flaming blade, the wielder taken on the form, and curse of the Fire Blooded Dragon inside, given them a relief from their suffer for as long as the wielder can tolerate their pain or finish using their powers. When Whitenaga was killed, she pass on her dragon saber, never knowing what it true power was to Nagra Omaga who anger over the lost of his first love awaken the burning flames of anguish as he destroy Kiljuro palace. It will be long after the Naga War and during the Chaos War before he learn the ability to shift into a Fire Blooded Dragon
