'Iblis' refers to a figure in a narrative; in the Iblisic narrative, Iblis is cursed and exiled by divinity for refusing homage to humanity. In taking this role, Iblis is a symbol that represents the umbra of divinity, humanity, and nature. Prior to this narrative, as a term, 'Iblis' might have originated as an epithet, with its broad meaning to persist in the face of the grief one has induced.
In anything deemed "Iblisic" we see some variant of the following:
1. There is an element of separateness [in a caste or from another caste].
2. There is a facet of exile or death [as imposed by oneself or another].
3. There is peril to a time, a place, or a group as a facet of an apocalypse [in the external world or even merely in oneself].
