The very act of contemplation can be a death sentence. Best to think of nothing at all, in most cases. - The Wizard Aldusessick

Light Worms are transdimensional creatures that manifest in Maradul as slow-moving spots of light. When another creature notices a light worm and believes it to not be natural light, the light worm will fizzle into nothingness and be destroyed. The "light" generated by a light worm emits no radiance, and will not illuminate any objects they come in contact with.

A light worm requires no actual sustenance to live, but they are believed to consume darkness. This act causes a light worm to shrink in size, which consequently makes them harder to notice and thus increases their chances of survival. As a light worm will increase in size as it ages, this becomes an absolute necessity. Light worms are believed by scholars to have a profound impact upon subterranean ecosystems.
