Welcome to the Myths of Life
They were angry. Angry about the humans. The vile humans. They despised them for having stopped believing in them, for becoming venom in the world, for destroying even what they represented; humanity.
Quick tides, earthquakes, and lava flows continue to strike even though the Gods have left this desolate planet alone to rot. However all is not lost. Four Gods have stayed behind, having not forsaken the world and believing the four key natures of Harmony, Freedom, Virtue and Balance are all it needs for the worlds to be restored to it's former state.
