Anon opened his door one night, greeted with a lone, mysterious book on his doorstep. Intrigued by the abstract tome, he perused the pages within. Varying spells related to cutie marks lined its aged pages, but one section in particular took him off guard.

A spell that could warp a pony's cutie mark, shifting it to a heart surrounded by chains. It would bend their mind, their life, their purpose to their assigned Master's will.

Taken aback by the entry, finding himself doubting its authenticity, Anon attempted to read it out.

Not to his surprise, he has no idea what it says - but he does know one pony who excels in cutie mark magic.

Story contains: Mind Control, lots of saucy Starlight action, casting an ancient forbidden spell, and a broken Pinkie Promise.
