A compact submersible of Eliksni design finishes its descent through the hazy depths of Titan's methane ocean. The craft's seafloor landing kicks up a cloud of dark silt and microbial life shimmering like stars. The submersible's dorsal airlock cracks open with a rush of bubbles, then slowly folds down into a ramp, allowing a trio of figures armored in deep diving gear to emerge.

Internal lights flicker on as the spire whirrs to life, creating a regulated field of water pressure around the submersible.
