Using the filament of a creature, you access that creature's long term memories that are contained within its identity. After performing the ritual, you can designate one topic that the creature might reasonably have knowledge of, such as where they were at a certain time the previous day.

As long as the event in question occurred more than 24 hours ago, you have a vision of the creature's memories of the requested event and see from their perspective. If the creature knows nothing of the requested event or topic, or the event was too recent, or their memory has been somehow altered, the ritual fails.
