Magic is the application, manipulation, and creation of energy using some sort of magically active biological or inorganic structure. For example, one of these structures could be some sort of organ which can control Umbra, as this organ can control, manipulate, and create energy, this is classified as a magical organ.
Organisms or structures that can control magic, or are heavily involved in its use, are known as “Magical”.
Magic can be applied to the Prime Material Plane with multiple different inorganic or biological structures. These are predominantly staffs, wands, biological organs, and most commonly Masks. Magic is common, as it in simple terms is just the creation and manipulation of a type of energy. As such, in some ways manipulating kinetic energy with technology, or just locomotion appendages could be considered magic on a technicality.
Ophanims are radiant predatory organisms which use auditory mimicry to lure and consume prey organisms. They are created when Radiance fuses with the stone obelisks found around the Empryean. Which they also happen to inhabit. Because of this, their primary locomotion method is levitating via Radiant energy.
They resemble large globular human eyes encased in orbiting stone wheels, which are denticulated and covered in eyes. They also have hundreds of angelic wings sprouting from these wheels, which although useless aerodynamically, harness Radiance to levitate.
To hunt, Ophanims will enthrall a town or small community in the lower Prime Material Plane. The Ophanim will use its ability to mimic the human voice and claim that it is God, or something else in line with the religious beliefs of the town or community it intends to enthrall. Usually, to do this it has to closely watch and observe the religious practices of the intended community or town. Once the town is enthralled, it will demand sacrifices. It consumes those sacrificed before promising a “Day of Salvation”.
This day of salvation is actually a mass consumption event. Once all remaining townsfolk begin the ritual, the Ophanim will return and begin the event. It will deploy multiple tentacles of pure radiant energy to consume the flesh and souls of the remaining townsfolk, damning them to nonexistence.
