Ingeitum means, Fire Worker or Blacksmith, in their language.
The clan is native to the Land of Mountains. They are unique because at the age of five, all clan members are bound to Dragons with the Ryūko Cursed Seal. Yūdai Ingeitum hails from this clan. Not much is known of their history yet.
Before the Series
Harizo Ingeitum was the Founder of the Clan. During the Land of Dragon's Civil war, Harizo ended the war by partnering himself with a black dragon named, Jierda and conquering the opposite side. Harizo invented the Ryūko Cursed Mark to fuse the minds of clan members and dragons.
Dragon Binding Ceremony
All clan members go through this at age five. They are taken to Blodgarm (血狼, Chi Ōkami; lit., Blood wolf), and they choose a Dragon, whom an Elder binds to them forever with a Curse Mark.
Meaning, Blood Oath Celebration, in their language. Once a clan member is a Jōnin, they make a contract with the Summoning Dragons and are granted adulthood.
