I_m a Deep Sea Cave Diver. The Safety Line Led Somewhere Impossible

DESCRIPTION:I'm a deep sea cave diver. The safety line is supposed to lead me back to the surface. But on my last dive, it led me somewhere impossible. A chamber that shouldn't exist. A passage that wasn't on any map. And something down there that was waiting for me. I've spent years exploring underwater caves, but nothing prepared me for what I found at the end of that line. I made it back to the surface. But I'm not sure I came back alone.
