We went rafting, but this is the closest we have to proof.

This story starts in the center of a city.

It's about four young men greedy for adventure.

Too much adventure, it has been said.

They were given directions,

and then took off,

hoping to get lost,

in the art and infrastructure,

of one city hidden underneath another.

They waded through waters,

found an abandoned tunnel,

and were never heard from again.
