Magestones
Stones that contain magic and can used to power magical artifacts such as the chandeliers used in Night Raven College, or by mages to control their magic use so they don't overblot as easily.

Magic Pen
Students at Night Raven College are issued a magestone that is attached to a magic pen that they use to facilitate their magic use.

Night Raven College's outfits all contain pockets for their students to easily carry their magic pens, with the exception of their ceremonial robes that instead have a key shaped carrier for the pens attached to their waist.

Overblot
Overblot is negative state that occurs if a wizard overuses their magic leading to "blot" accumulation exceeding their magestones. During overblot Phantoms are created to drain the user of all their magic, leading to their death.
 * In Episode of Heartslabyul, it was shown that one of the side effects of overblotting is the victim starts leaking black inks from their head as they kept overusing their magic to corrupt them further.
