(Sorry! Demise's player has been absorbed into her DS an fanfiction writing lately. Some plot-catalyst coming up!)
Demise landed his Loftwing on a high cliff overlooking something that made him sick. The mortals were becoming too proud... impetous. The green valley below was supposed to be a sacred area, reserved for the gods. There was a human settlement being built right near one of the rivers Lady Hylia liked to bathe in sometimes. He sometimes liked to wash up there, too, but that was not the point.
Mortals were to keep to certain areas. Sometimes, it was for their own protection, sometimes it was to protect the land itself from their inevitable disrespect in its use.
This village was far too close to a large lode of Timeshift Stones, too.
"I need you as a sword, Ghirahim." Demise ordered. "Return to your native form." He then smiled a smile deeper than darkness. "You are going to get a taste of blood today. Have fun. Drink your fill."
He took one last long look at the village before embarking into it. These mortals would learn the price for defying the gods. They would meet him, their demise, early.
