Synopsis
cast 'stifle illumination' [<victim>]
Description
Light is an important and omnipresent aspect of life- whether sunshine in Alyria, the incandescent fungus in the Underground, the crystal prism in the Sigil Underground or the background glow of the Faerie Plane, nearly all sentient races life in the light. To magically suppress one's light is to deprive them of their sight, leaving the sighted vulnerable.
Magically stifling illumination involves rendering the target's light source unusable for a short period- the will either be forced to use a different light source, or go without until the magic wears off. Because many light sources are magical rather than being literal physical flames, the victim has a chance to maintain their light if their personality is great enough to maintain the link to their light source.
