The Shadow Seal is an ancient artifact used many years ago to banish the very powerful demons from this dimension. After it was used, it was broken into twenty pieces and scattered across the globe. For if it were assembled someone could use it to undo the banishment on a specific demon, allowing them to enter this dimension. If used in this manner it does not create a portal or summon the demon, they must still find their own way into this dimension, but they are no longer banished from it.Buffy TVS Items
