Vinyl Scratch and Lyra Heartstrings are vampires, creatures of the night whose civilization has lived in humanity's shadow for thousands of years. They are self-sufficient and prideful, only venturing out of their hidden cities to replenish their stock of blood. But ties to past lives are not so easily severed.

When Lyra catches wind of supernatural happenings in her hometown of Canterlot, she and Vinyl take it upon themselves to investigate the cause.
