In the modern-day dystopian world, Insulam, the rich and the poor are more divided than ever before.
With Class 1 living in luxury apartments deep within the main city of Insulam, being able to live freely and enjoy the luxuries of life, they are closely affiliated with the corrupt government, getting whatever they desire while subjecting the working class further down the "Caste System".
Class 2 on the other hand is also able to experience these luxuries, however they are much more humble about the lives they live.
Class 3 lives mainly in alleyways near class 2, always making sure to stay out of sight from those in class 2. Those in class 3 begin to suffer from the work they provide towards classes 1 and 2, benefitting the upper class as opposed to benefitting them selves
Similarily, class 4 citizens also suffer from the work that they provide to the upper class. However, the work is more arduous than that of class 3. Citizens in class 4 must carefully ration their meals in order to survive
Last but not least, in class 5, citizens undergo similar conditions to those of class 4, however they barely survive here. Living in their own workplace, they find difficulty in searching for shelter, food, clean water, etc. The work in class 5 is the most rigorous and tough. Despite the majority of the population of Insulam living in class 5, millions still die each year from these harsh conditions.
