This mountain lake of icy water is nestled in a bowl-shaped valley between three peaks, fed by the runoff from a glacier of blue ice high above. When a believer throws something truly important and valuable into the tarn as an offering, a light rushes up from the incomprehensible depths. When the light reaches the surface, it takes the form of a prophecy featuring the supplicant-or a powerful archon to deal with the intruder if the offering was not sincere.
