The following account was recorded in the agent's log during your transmission: A huge, uh, abandoned lighthouse somehow stands in the middle of... a massive impact crater filled with water, like a lake. The air's heavy with the smell of, like, damp earth, and the sky's a weird, flat grey, like it's overcast but you can still see the sun's position, umm... mid-afternoon maybe. Echo, come on, keep going... somehow... Water flows up the lighthouse's crumbling stone base, which appears to be, like, filtering it – the liquid comes out clear on the other side, somehow.
