The following account was recorded in the agent's log during your transmission: Umm, schools of bioluminescent jellyfish illuminate a series of underwater geodesic domes, casting an ethereal blue glow across the seafloor. The water's pretty still, except for a few stray currents rippling past the domes, and the air pressure's extreme. Each dome contains a perfectly formed, miniature replica of a different, ancient megalithic structure - like Stonehenge or Carnac stones - somehow crafted from coral and shells. Water droplets are suspended mid-air within the domes, as if time's been paused inside.
