The Seeding

Geological / environmental event

The Elder Gods take physical form.
  The Elder Gods seed themselves onto the planet - splitting into thousands of physical avatars to feed off the new life being formed. These take the forms of the original abominations and demons.
  In this age all are tied to the consciousness of the Elder Gods./ Slowly over aeons, these avatars of the Elder Gods grow more independent and self-conscious. Through greed, gluttony and slothfullness, they become earth-bound and lazy.
