Dark Spiritons

Dark Spiritons are housed within the Shadow Void, a dimension between dimensions that acts as glue for the Dangai Precepice. Their gravitational force allowing to repel the spiritual skin of the dimensions, keeping them from bleeding together.

Dark Spiritons absorb photon(light) energy, this makes them appear black.

Dark Spiritons are also seated with all Darkness and Shadow Zanpakuto abilities.

Standard Spiritons are a mimicarry energy, their protian form allowing them to alter and change their electrical signiture and magentic force to mimic the form and effect of almost ANY substantial form. For example: A Hadou Yo(4): Byakurai(White Lightning) is not REAL lightning, its spiriton energy mimicing the form and effect of lightning.

However, Shadow and Darkness do not have substantial forms, they are a lack of substance, so normal Spiriton energy is ill equipped to mimic their form.

All Shadow and Darkness Zanpakuto have, in some way, no matter how directly, or indirectly, a link to the Dark Spiritons of the Shadow Void
