why they are hated (partial explaination)

To be honest, there had been another species of Drakkotas. It had been a water species derived from the blue Drakkotas. More beautiful, delicate and slightly weaker.

They had been driven out by the third ruling matriarch of the blue Drakkotas clan for being too weak and coquettish. The ruling Matriarch at the time had believed the strong are only valued. She had also slaughtered many of the other clan Drakkotas; red, black, white and grey even if they had tried to join forces to retaliate they were too weak to defeat her and were divided and defeated forced to retreat. They had been at that time defeated to the point they had to take several centuries to recover until it was over four thousand.
