This ornately carved golden sphere is about 2 inches in diameter, and functions as an Ioun Stone. When active, it senses and records significant events that have taken place near the bearer's current location. While recording, the event being recorded is shown as a faint illusion, and can be seen and heard by anyone in the area. The bearer can also command that the Chronominer show events that it has previously recorded.
There is no known limit to the capacity of a Chronominer.
