Clock Tower of Aquunus
From ThresholdRPG Wiki
A tall wooden tower that reaches thirty feet into the air and measures about ten feet along each of its four sides. This tower rests in the center of the city of Thrace.
It is speculated that the clock tower runs by some combination of water and mechanics. Its machinations are unknown, as the tower is tightly sealed by enchantment and nobody has ever seen the inside.
At its pinnacle, on each of its four sides are two boards which shift as time passes, bearing stylized numbers denoting the current hour.
