The following account was recorded in the agent's log during your transmission: Schools of ghostly jellyfish pulse through the darkness of a derelict underwater oil rig, their ethereal bodies somehow impervious to the jagged metal debris scattered everywhere. The air's thick with the smell of saltwater and diesel fuel, and it feels heavy, like the pressure's extreme. A steady hum, almost like a chant, emanates from the rig's central well, which appears to be sucking in the surrounding seawater at an alarming rate, creating this weird, swirling vortex that's pulling in all the nearby fish... Uh, the jellyfish seem to be migrating towards it.
