The Doom Fang is an organise group of dragons form by the Great World Ender; Le Ghaster. Le Ghaster was said to have been a 'fallen god', which is not often believed, but it is true that he slowly formed The Doom Fang from the outcasts and rebellious dragons from the tribes. The process took 4,000 years and resulted in the creation of the largest and most powerful of the tribes. This all took place before The Scorching around 11,593 years from the present. 

The Doom Fang were once resented by the other tribes as it had represented all the outcasts and deserters of the tribes, but due to The Doom Fang having the most advance tech, knowledge and abundant resources, a mild alliance was formed. This was strengthen when Crimson Slash had made a proper alliance with the Doom Fang. 

The Doom Fang mainly live on the scatter island, underwater caves and the continent of Ragnorak, a continent at the south that have extreme climate temperature  from extra cold ice sheets to humid tundra and icy waters. 

No one knows why the Doom Fang didn't participate in The Scorching or why they vanished from the continents of Pyrrhia and Pantala. However, we know that they aren't dead as the Grim are still connected to them. 

From what we know of so far, the current Ruler of the Doom Fang is King Le Ghaster.
