Eternals

Minds transcend the limits of a biological body to become post-organic beings, machines that call themselves Synths or Eternals. Most are content to amuse themselves, becoming Puzzlers, or turning themselves into works of art as Creatives. But some - led by the Shining Knight - decide that all Synths, including themselves, are Abominations to be eradicated. So, the Shining Knight sets out to destroy all Eternals. Is it right for these beings to be wiped out, or are they sentient and deserving of life? Now humans no longer exist, who can make this decision? More importantly, who or what can oppose the Shining Knight?
