/imagine: While paddling down a river like the Amazon river, we see a massive 300-foot-tall, narrow spire made of bricks and rock, with smoke issuing from a flaming beacon at the very top of it. This spire is seen from the distance, rising high over the top of a dense jungle canopy that resembles the amazon rain forest. The walls of the spire are sheer and dotted with small caves and a few frail-looking ladders. The spire is at least 5 miles away and we can't see the base of the spire.
