The Sun, Moon, and Bell Lock

The ruin opens into a circular chamber where dust lies in perfect rings around a brass apparatus half swallowed by ivy and age. A three-ring dial gleams dully at the center of a stone plinth, flanked by a lever whose iron grip is worn smooth by old hands. Three brass tokens rest in niches nearby, each stamped with a sun, a moon, or a bell. When the machinery is touched, it wakes with a dry ticking, a pulse of warm air from hidden vents, and a soft tremor through the floor as if something sealed below is trying to remember how to breathe.

Checks

Intelligence (Arcana)12 Intelligence (Investigation)
Notice wear patterns, residue, and the intended order of the controls.
Dexterity (Thieves' Tools)12 Intelligence (Arcana)

Wisdom (Perception)13 Dexterity (Thieves' Tools)
Bypass a jammed gear, hold a slipping pawl, or reset the mechanism after one incorrect input without triggering the worst backlash.
Intelligence (History)10 Wisdom (Perception)
Spot the tiny indicator marks on the brass plates and hear the click that confirms each correct step.

Overview

Discovery

The puzzle is noticed immediately in the center of the chamber, but the correct order is discoverable from the wear marks, the engraved instruction plaque, and the chamber's audible feedback when the controls are moved.

Brass Plaque on the Plinth

Turn the wheel in the old order:

Set the sun where the warm socket lies.
Let the wheel find the moon after the sun.
Let the wheel find the bell after the moon.
When the ticking becomes even, draw the reset lever down.

If the wheel complains, do not force it. If the lever resists, the order is wrong. If the chamber grows warm, begin again from the sun.
