Iuchi Zeshi

Iuchi Zeshi was the son of the Iuchi Daimyo in the 10th century, but he lacked the gift to speak with the kami. Zeshi served his clan as armorer, a gifted leather-worker, and was granted his own vassal family, the Zeshi. They provided the clan with the bulk of its modern Unicorn Riding Armor.
