Jiao

Jiao is a spirit summoned by the Godfelling Crossbow.

Jiao is a figured related to the legends of Qin Shi Huang and Xu Fu. Notably, Qin Shi Huang was the one who killed him using the crossbow, after trying many other Mystic Codes to do so, because they impeded Xu Fu’s voyage on the orders of Qin Shi Huang to search for immortality. They were once called a deity, a sea god, and once had a name long ago but have since "lost it". "Jiao" is the name they give Sigma to call them by.
