Celestial Solaris is known as the Guardian of the Multiverse. She was created by the entity we know as 'God' in order to protect and cleanse his vast and expansive universe of the pure dark evil lurking within them. She only knows how to slaughter, strive, and create allies.

But what happens if 'God' sends her to the peaceful lands of Equestria where warfare or evil is not present?

And when she meets a lone human living on his own in Equestria?

!Warning! It is highly recommended that you have knowledge about the game Mass Effect as the story will include lots of references to that game and loads of spoilers.

Princess Celestia and Celestial Solaris are two different ponies.
