Blank Magic is introduce in Equestria Girls: My Noble Steeds, created by Sir Shroud.
Shroud find the designs for Twilight Sparkle's magic capturing device she used during the Friendship Games. He made some improvements to the device with the aid of Professor Discord's obscure algorithms to make better on capturing magical energies. He also created a filtering device to attach onto the Humane 7, in order to take samples of their magic and extract the unique qualities from them to create "Blank Magic". With the aid of a specially built reactor, Shroud can produce more out of the samples.
When infused with a host, the Blank Magic change and morph into that of their Equestrian counterparts.
Blank Magic is notified of having a Dark gray aura.
