The culture inside island was always original and it is considered weird in modern civilization. People inside the island had no name. They were addressed by the name of their occupation. Every people hunting was called hunter. Every healer was called healer. Every one guarding the base was called guardian and everyone incharge of war was called warrior. They didnt discriminate age or gender of people. There wasnt a way to mark different people or actually there was no reason to do so. The occupation of everyone was decided according to when they are born and that is how they gets their name.
People in the isolation was more like animals. They had no marriage no agreement with others and anyone was sleeping with anyone as long as no one objects. People usually dont object about anyone wanting to sleep with them at most they asks for some patience and agrees to sleep some other time. And when someone is denied they dont mind as well because there is many options for everyone.
All the three tribes living in this isolation had these things common. The idea of people being a seperate entity was never present in the unknown. Every single person was considered as the whole of tribes they belong, there was no ruler yet everything was smooth and peaceful. The island was called floatation.
The most ancient thing about the island was it being called floatation by its inhabitants. It was the only thing that had its name in the unknown isolation. Even the tribes didnt have proper names. They were called fish tribe, corps tribe and cattle tribe. People of the tribes were free to change their tribes whenever they want. Tribes were more like a lifestyle there.
Another weird part of the island is people rarely using language in the floatation mostly they communicates using facial expression and sometimes using telepath...and they hardly uses written form... Their elder says everything we cant remember is not worth remembering...
People gets their names that is their occupation according to the time and day of the year they are born. There is no watch to check the time so its more like a assumption there. But they memorizes the days, months and years. The rarest of the name that one can get was the oracle and one of them named the floatation long ago.
