Note- The story isn't that dark.

This story was written with my friend, Godzillawolf. After stumbling upon a homeless Trixie, Twilight tries to help her get a new job in Ponyville. However, an unexpected visitor to the town wants to leave Trixie homeless and feeding off scraps. Checker Monarch is set on ruining everything Trixie does, for reasons not yet explained. Trixie must discover new friends and must face this old danger through new eyes.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?
