One of the most interesting thing about this city is that it is constantly moving. The water turbine, along with powering the city, acts as a motor keeping the two main pipes constantly slowly moving, making the other parts of the city hanging from these rotate. The city rotates once a day, allowing the population to use there location as a reference for the time. The pipes which hold the city up in the air are not only a structure to allow the city to be in the air but being hollow on the inside and flattened along the bottom these are used as roads, allowing the residents to travel to different parts of the city protected and with ease.
The people from the city rarely step foot on the ground. The only occasion this happens is when food is scarce. The main food resources for the city are birds from the air and fish from the water, along with fresh vegetables grown in one of the towns. Many of the people in the city are skilled with bows and arrows and use these to catch their own birds. They use a specially designed bow with a line and reel to allow them to easily pull in what birds they catch. The fish come from a part of the city which acts as a fishing village. Constantly through out the day they raise and lower giant fishing nets pulling in large hauls of different kinds of fish from the fast moving waters below. These food sources are usually enough to support the whole city through out the year. At times food from the air can become low due to birds migrating and this is when the towns people will go to the ground to hunt. To get to the ground there is a large lift along the inside of the main pillar which can transport several men and equipment up and down. The people of the city use traps to hunt as this allows
them to be on the ground for as little time as possible as they feel threatened from all of the dangerous animals that inhabit the jungle. They go to the ground, set as many traps as possible within a time limit they set depending on how much food the city is in need of, then return to the city for the night, checking the traps in the morning then returning their catches to the city.
The buildings of the city are the most important part of the cities structure. This is due to them acting as counter weights keeping the pipes level. The shapes and weight of the houses changes from town to town and generally from house to house, each being slightly unique in their own way. Above the two main poles which make the city is a small building held up by a think pillar going through the two pipes all the way to the water generator. This is the cities main control tower. In here they control the cities water intake and filtration from the river. The electricity provided from the generator and the distribution of this electricity. They also watch the cities rotation keeping it as a constant speed at all times. They also act as the cities security controlling the lift, the only way of accessing the ground.
The city of Calder is not an easy one to get to and once getting to is almost impossible to actually enter, the security will rarely let someone who is not a resident into their city as they find other cultures a threat, after being secluded for so long. If lucky enough to get inside you will witness the calm and kind nature of the people who live there, thriving off each other and providing a safe haven for everyone who lives in this secluded city.
