The Arrival of Demise

'When the gods of old left the world they created, they trusted their ultimate power, the Triforce, to the hands of Hylia so that she could protect it. She did so throughout the Era of the Goddess Hylia until one day a crack opened up in the earth and the Demon King Demise and his demonic hordes came forth from the fissure...
In order to prevent the great power from falling into the hands of Demise, Hylia gathered the humans and sent them skyward with the Triforce, beyond the reach of evil forces wrecking havoc upon the surface world.'

The demons came out of the earth but I made them come from the sky instead, oops!
