The Pearl of Judgment was a Naga pearl which cast an air spell of Mastery 4 (Defense) that linked the caster to a single target and achieved a state of complete communication. The caster might ask a Naga one question and know if the answer was truthful. If the target was not a Naga, he became overwhelmed by the touch of the Akasha, and the caster was treated in high regard by the target for any courtly endavour during the duration of the spell.
