Magic Sealing Stones is a Magic Item used to imprison Mages.
True to its name, Magic Sealing Stones are used to construct prison cells out of Magic stones; utilized to incarcerate Mages: rendering their Magic abilities ineffective when inside (e.g. Cobra's Sound Magic), including noteworthy Mages of preeminent Magic Power such as former Magic Councilor Jellal Fernandes and the Dark Guild Oración Seis. However, Mages are able to inflict damage upon imprisoned prisoners from the outside, displayed when Nadal heavily tortures Jellal Fernandes with a Magic beam from his Magic Staff. Albeit, prisoners can be easily released by outside forces, such as when Lapointe assists in the Oración Seis' escape with his Personification Magic without the Magic Council noticing. The sealing stones also come in the form of handcuffs and shackles, which can impede the person from moving while also nullifying their Magic.
