Surface dwellers use these brass timepieces to track the passage of time in the Darklands. When it's wound with a small key, a cover rotates across the dial's face, revealing a sun and moon that indicate the general time over the course of 24 hours. Each turn of a key adds 1 hour.

Some clockwork sundials are crafted to have a duration of 60 minutes, with each turn of a key adding 10 minutes.
