The following account was recorded in the agent's log during your transmission: The air's heavy with incense, and a series of cryptic murals on the vaulted ceiling of a vast, Byzantine-style cistern depict events from the Book of Enoch. Water drips from the crystalline stalactites, reflecting a kaleidoscope of colors in the faint, ethereal light that permeates the space. The sky above, visible through a massive, unsupported dome, shows a perfect, concentric arrangement of rainbows around a black, solar eclipse... the air's still, and the water's surface is calm, but the sound of gently lapping waves echoes off the stone walls.
