Appears in: Uru
Found in: Bevin, Relto

Clocks of this type are found in public gathering places in the D'ni Cavern, such as the Bevin neighborhood. Another such clock can be seen on an island in the personal Relto Ages of explorers who have activated the clock gift from Yeesha. However, the Relto clock is nonfunctional, and is decorated differently than the Bevin version.

The gorahyan (gorayån) has a globular display held in a semi-meridian mounting raised on a pillar or stanchion. A band around the equator of the globe is marked with the D'ni numerals from zero to twenty-four, representing the 25 "bells" of the D'ni day, with a dot midway between each numeral. The zero bell is represented by the "wrapped zero" numeral, used in circular displays. Each bell period is about 72.5 minutes of surface time, or 5 tahvotee in the D'ni system. The number of the current bell is viewed through a magnifying lens mounted on the front of the gorahyan, and the globe turns clockwise as viewed from the front.

Historical documents (see Myst: The Book of Ti'ana) mention the sounding of the bells from public plazas in the Cavern. However, if the gorahyantee were the source, the mechanism is no longer functional in the Bevin neighborhood, despite the fact that it is still turning.

At this point it is unclear if the term "gorahyan" applies only to these clocks, or if it can be applied to other timekeeping devices, such as Aitrus's watch, Gehn's watch, or the timer in Kadish's office on Ahnonay. The term might even be broad enough to apply to a calendar, though no example of a D'ni calendar has yet been seen.
