This ritual alerts members of the great race of Yith in the caster’s own time to the caster’s location and desire to make contact. The ritual cannot contact such beings in the future or past, only members of the great race who have mind-swapped with a “native” intelligent creature in the present.

The Yithians gain familiarity with the caster as if they had firsthand knowledge (for the purpose of scrying and similar spells) and familiarity with the caster’s location as if they had seen it once (for the purpose of teleport and similar spells). The Yithians otherwise gain no special ability to travel to the caster or communicate. The Yithians may choose to approach and interact with the caster if such interaction seems safe, productive, and interesting. They will terminate persistent or irritating casters they do not trust by whatever means at their disposal. From negative experience, Yithians are wary of being interrogated and tortured for their vast knowledge, and their knowledge of all time makes them adept at judging whether any particular caller will prove such an interrogator.
