“I had no idea what I was doing, all I wanted was to protect my sister. I couldn’t find a healing spell guaranteed to work… So I went a different path. I didn’t actually heal Rarity at all… I gave her body a new source of life, my own.

No one knows, but her life is tied to mine now. If I fail to perform the necessary rituals, or if my magic gets taken away from me, Rarity will relapse… And the bond will be broken.

It’s too late to reverse it now. There is nothing left in Raritys body to save. I am pretty sure my magic is the only thing keeping her alive at this stage.

That’s why I can’t stop.”
