ESF: Galaxy & Nightmare 2: Battle Between Brothers
by The 14th Doctor
First published
After pondering about what Nightmare Moon once said to him, Comet decides to free her along with an old foe the Mane 6 have fought before. Apparently, Comet's time as Nightmare Spiral had changed him to the point of no return. Galaxy never expected his most hated enemy to be his own brother. Now torn apart emotionally, Galaxy must rally his strength one last time to save Equestria. This time, he won't have the aid of his friends to back him up, because Comet intends to handle Galaxy alone, even if it means his brother's life.
Prequel is highly recommended for story line
Written in Vanilla Mocha's point of view
Rated Mature for language, suspense, frightening moments, and slight gore
Sex tag added for some....off-screen fun-time between Comet and Nightmare Moon, no actual clop is featured though
