Clocks

Clocks of the surface-dwellers of Durath mimc the appearance of Caluminor in the sky.
In simple terms, such a device consists of a small powered mechanism to rotate an orb (or a cylinder, in some eccentric styles). While decoration and markings may vary, the orb is split into two hemispheres - the light and dark faces of Caluminor. At midday, the dark face is shown in full, and at midnight the light face is shown in full.
Common adaptations on this basic design include hour markings, aesthetic features to mimic the band-like features of Caluminor, and intricate framing.
Further mechanisms to count the cycle of the year are included in more extravagant examples, and necessarily depend on the calendar being followed.

While it is possible for clocks to be produced in miniature, portable form, the practice is rarely persued and is considered an extravagance. Because of the intricacies involved such examples are either expensive and fragile, or shortlived to the order of a month.

Utility

Although useful in almost all settlements, the impact of the clock has been most felt among sub-surface cultures, where a glance at the sky to determine the state of Caluminor is an impractical undertaking.

Manufacturing

The manufacture of clocks is most commonly undertaken by the clergy of Xoorr. Creation of a divinely-powered clock is one of the required tasks set of an apprentice, on their route to mastery.

Access & Availability

Any temple of Xoorr is likely to bear a clock on a tower or mounted above the main entrance. This serves as a symbol of worship, an asset to the community, and a display of the prowess of the clergy in residence. They are usually attached to bells, or other sounding equipment, to signal the time of day to the community.
