War is coming. This complex structure of the Watchtower plays an important role. It is built block by block from gray bricks, and is reached from top to bottom by a spiral staircase without protective railings. A huge oriental dragon is wrapped around the entire spiral staircase. It is alive but fixed in place all year round, responsible for looking into the distance.

The base of the tower is not the bottom of the entire space. There is a wall below the tower, several hundred meters above the ground, and next to it are ancient European-style residential houses. There are also train tracks built into the wall. The train will run on top of the wall, shuttling between the various Watchtowers.

Walking up the spiral staircase in the tower, you can reach the top of the Watchtower - the highest point in the entire space. There is a huge flag on the top of the tower, a red pennant. The most special thing is that there is a pool here. The depth of the pool cannot be estimated. The reason is that there is a giant octopus in the pool, which fills the entire pool, so the bottom of the pool cannot be seen at all. The water in the pool is not clear, but the shape of the octopus can be barely seen, as well as its eyes that glow yellow.
