Masquerade Artifacts

Artifacts which can be used to masquerade people, objects, or places. Disguising something from notice or changing its appearance qualify as well. Illusion-creating is also placed here (specifically illusions, not physical creations). Artifacts which reveal these illusions are also placed here. By extension, mental constructs primarily regarded as delusions and hallucinations fall under this remit, as they can transform a person's sense of perception instead of the environment itself.
