Noor is an anthropomorphic anglerfish who lives in the idyllic kingdom of Ellycium, where he leads a peaceful life gathering gemstones and worshipping king Quzah. Noor's life is pretty uninteresting except for the fact that his esca, the colorful orb floating above his head, is rainbow colored, unlike the rest of the anglerfish who have unicolored escas.

Noor's distinctive esca color, coupled with certain unexplained events and rituals in Ellycium, push him to question his own identity as well as the reality behind the kingdom's myths and mysterious king. His quest for truth causes division among the anglerfish and leads him on a journey to the legendary emerald mountain of Kaf where he uncovers some astonishing secrets about the true ruling cabal and about himself.

Inspired by Arabian mythology and Sufi beliefs, this story explores the mystery of the spiritual aspect of existence and the theme of uncontrolled technological progress.
