Veildust

Veildust, as it has come to be known, is an ultrafine powder substance that causes hallucination when inhaled, ingested, or otherwise induced into the bloodstream. Little is known beyond that, since its psychoactive effects make it difficult to study. Some curious properties include its ability to permeate hermetically or magnetically sealed environments, its visible glitter even in densities too small to be noticed by the naked eye, and that there is no theory as to how it is produced. Places it has been found are on planets, nebulae, and derelict spacecraft.
