The Triptych of the Silent Sovereign - AI-generated fantasy Puzzle

The Triptych of the Silent Sovereign

At the end of a corridor choked with the smell of dry earth and bitter almonds stands a heavy limestone door. Three concentric stone rings are set into the surface, each etched with crude icons that seem to glow with a faint, sickly green luminescence. A single bronze basin sits on a pedestal before the door, stained with the residue of ancient offerings. The air here is unnaturally cold, causing your breath to mist as you approach the cold, silent stone faces of the mechanism.
