This story is a sequel to Oh God They're Dead They're All Dead They're All Dead They're All Dead

Starlight found a spell in a spellbook, specifically a book from a certain dark unicorn of the north.

With determination in her heart and mind she knows she can not only cast it, but improve it to benefit Equestria.

A sanctioned prequel to a story that was really good, but left too open.
I'm honored to do this.
