It is told that the scattered families of the Chi are the descendants of an older clan, that their prowess exceeded that of a hundred clans. It is often said that the Chi clan once manipulated not only blood but pure iron and slaughtered a thousand clans this way. This, of course, remains a mystery — a tale passed down from one head to the other. And like most tales, it is nothing but wishful fiction.
From an early age, Chi children are taught tradition and integrity; manners and humility. The clan believes a conservative upbringing to be the best, and often slaps heavy expectations upon the younger members. This implies physical and katana training, mental conditioning, and etiquette schooling. Failure to meet expectations often results in ridicule and minor punishments such as extending the lesson or depriving the Chi of food. It is why weak Chi members with an iron-deficiency are often said to be rebellious and insubordinate.
Coming-of-age ceremonies are held when the Chi becomes nine. If they have mastered the Blood Bending Technique they are congratulated and a celebration is held for them. On this day, they are also — per tradition — instructed to slay a smaller creature with their own, manipulated blood. This suggests they are half-way into becoming full-fledged Chi and brands them not only proper, but strong. They are then enrolled in the academy, and — when they finally muster the courage — they can choose to become a full-fledged Chi.
This happens when the Chi spills the blood of a loved one — or, in practical terms; takes their life.

Blood Bending Technique Chi are able to bend their own blood and alter its shape so that it may resemble a weapon or a shield. Variation of these shapes depends on the volume of blood that the Chi extracts. More advanced members are able to exude larger amounts (and therefore a larger quantity or a larger shape) of blood.
