The Real Reason We Have Risar

I'm shocked that no-one has suggested the obvious:

  • they used to steal Human children and eat them
  • then started breeding a captive population
  • those humans eventually escaped after many generations of warped and warping existence to become the Risar-- which would explain neatly why Risar and Humans can interbreed, and why Risar think nothing of keeping slaves themselves.
  • Mushrooms![1]
  • Profit.
