Temple Bridge

We are in an ancient temple, carved in a cave, made of big black stones. An immense passage above the void, a 7 meters wide by 20 meters long. This bridge is composed of huge slabs on which are engraved capital letters. The letters are in 5 rows, 14 columns. Here are the letters: A M D J A O V L S R M I O X, F U I P M I O D S K E H G J, S Q S S - M F J V H R M Z P, J D K C G L I O C P N X I N, J Q A I E B E - S J D K F G. The floor smokes from place to place. Far far far below the bridge, a red glow coming from lava. After the bridge, some stairs are going deeper in the cave.
