Characters
The Javanese have various philosophies as a guideline to achieving perfection in life, one of them is Sedulur Papat Limo Pancer.
This philosophy guides for a human to appreciate and control their emotions along with their activities or dealing with daily problems.
Sedulur Papat (the 4 siblings) represents the 4 human emotions or desires consisting of amarah (anger), lawwamah (greed/gluttony), supiah (lust), and mutmainnah (sloth).
Limo Pancer (the 5th is the center) represents body itself as the controller of the four desires. This concept is acculturated to Djinn Qorin, or literaly translated as Soul Siblings.
