A tool in Twisted Wonderland. It's given to students of Night Raven College in order to help channel their magic and control their blot. It physically appears as a pen with a magestone (gem) in the color associated with their dorm. It can be used as both a wand and a writing instrument.
Instead of a magic pen, Grim wears his gem on a collar around his neck. Silver Vanrouge's magic pen is larger, making it more closely resemble a dagger. Idia Shroud and Ortho Shroud do not utilize them.
Students at Royal Sword Academy are shown to also keep their magestones in their lapels, but it's unclear if they also function as pens.
