My idea is to add powerful species created by the Endless, those creatures would be later be called "Cosmic Creatures".

Cosmic Creatures are hidden on isolated parts of the galaxy, some may hide on an isolated places of the galaxy.

When someone finds it, they have various different looks and options according to the type of Cosmic Creature, there are 3 types of them:

  1. Combat: Try to recruit it  or Kill and harvest it
  2. Plant-Like: Study it or Preserve It
  3. Influencial:Worship It or Try to communicate with it
