The Koon family symbol

The Koon Family is one of the 10 Great Families. The head of the Koon Family, Koon Eduan, is said to have the most "wives" (married partners) of the 10 Great Families, so the family itself is very large.[1]


Because of the large number of wives and children Eduan has fathered, there is a lot of veiled competition among the children of the family; too much competition has created the 'official' fights.[1] It is held once a year, with the following rule: 'When the children of Koon reach the age of 10, they are to fight each other. The winners are recognised as the true children and are allowed to wear the crest of the family, but the losers become the 'abandoned' and do not get the crest'.[1] Although the fights are inhumane and bloody, Eduan himself says he's "not very interested".[1]

Additionally, there is likely a lot of competition among Eduan's wives as they seek to gain favour with and power from their husband. It was mentioned that "the powers have shifted" and Koon Aguero Agnis' mother said she had "lost the fight" (for power).[2] The "house head" that was mentioned to be the person who was responsible for "casting aside" Koon Aguero Agnis[2] is likely a person who holds a high position within the Family and could even be the wife of the main branch.

Those from the Koon Family tend to be clever, but quite cold-hearted schemers. They also tend to be quite confident and proud people. Due to Eduan's bloodline, many members are inherently strong. They all seem to be trained with Shinsoo and physical combat before entering the Tower as Regulars.
