The following account was recorded in the agent's log during your transmission: Black water's churning against the rough-hewn stones of an abandoned, cyclopean harbor, its surface somehow covered in an intricate network of hexagonal cells that reflect the pale, early-morning sun like a layer of oil slick. Umm, the air's crisp, heavy with salt and the scent of seaweed, and this... this low, keening hum is resonating through the water, causing the hexagons to quiver in synchronization with a massive, crystalline growth that's bursting from the seabed, sending shudders through the ground. Water from the harbor is somehow being siphoned upwards into the crystalline structure.
