Isith

(a.k.a. Jeiru)

Very little is known about the being known as both Isith and Jeiru. They were cited by Vhyr-mäd to be a warlord, leading the elemental army during their siege.
They are believed to be the entity which Terestri's parents worshiped, and intended to sacrifice him to. The symbol on the book Willow first found about Isith was the same symbol Faelyn Ar'aphine showed them, what had previously been branded onto Terestri.
They are allegedly affiliated with the Burning Emperor, Isatum.
