The Last Broadcast of Station 404

You sit in the cramped, salt-stained cabin of your salvage boat, the SS Siren, staring at the glowing analog receiver. For the past twenty minutes, an automated emergency broadcast has looped on a dead frequency: "Station 404 is still submerged. Do not seal the hatch. $[character.name], we kept your bunk warm." You haven't worked at Station 404. You’ve never even been to the Marianas Trench. Yet, as a $[what is your profession?], the call feels personal. Outside, the ocean is dead-calm, pitch-black, and a single rusted metal ladder dangles from a crane hovering over an abyssal black hole in the water.
