In C. 9100 PT, A gigantic dwarven coalition marches upon the Elven lands of Fuscus, which was then an ancient forest covered in towering trees.
The Dwarves and Elves still tell different stories of why the attack took place. The Elves claim the Dwarves lusted after the splendour and power that the Elves possessed. That their lust for wealth had finally lead them to attempt conquer the Elven Realms.
The Dwarves claim that the dwarves were dying to a viscous plague, and the elves had the means to stop it, but withheld it from them. Thus they had no other choice but to try and force their hand.
Another story, seldom told, is that this was Seó's first scheme. That he was born of this treachery, no matter which side of the story one believes, and that he fed it, like an unbreakable cycle of deceit.
The result was the complete destruction of the oldest Elven Realm on Kosmós. The land of Fuscus shattered in the battles, were the gods themselves threw themselves into the fray. Raka and Tuma, the gods of Roots and Growth, cursed the Dwarven host in Fuscus, those dwarves that remained in Fuscus, were swallowed by the very earth they burrowed into. It is said the blood of dwarves is what makes the many rivers of Fuscus glow its infamous eery red.
