After making Angels recently, the word Jinn suggested itself quite naturally. The word I used here is actually jinni جنّي, singular form of jinn.
There is no better scholarly source for jinn studies than Ibn Arabi (whom I discovered years ago while researching jinn, precisely, for Malaak – a whole other line of thought). Without getting lost into pages and pages of discussion, I want to point out that the primary meaning of the word jinn is "hidden, invisible to the eye", which is why he describes 3 ways of understanding it as mentioned in the Qur'an:
1- God created 3 races of rational beings: Angels, Jinn and Men. Jinn are intermediate beings between the spiritual nature of the former and the earthly nature of the latter. They belong to the imaginal, the world of archetypes, and this may be why they are said to inspire artists and poets (Arabic even has a verb, waswis, to refer specifically to jinn whispering in one's ear) 2- Jinn is a general term referring to "all that which is concealed: angels and other beings". 3- The jinn refers to the invisible part of the human being, their inner world, as opposed to what is visible of them (body, actions). These may not be be mutually exclusive, but can be seen to point to a complex, interpenetrating reality.
The notion of concealment, of elusiveness, drove my design: the word must be there, but where is it? An interesting detail: the design is twelve-fold, but it is only after finishing the piece that I came across the quote; "It is said that jinns were originally concentrated in twelve tribes...."
The HrrngŁ Chuzho (or Hrrngy Chuzho depending on transliteration conventions) script, was developed by a religious sect known as the New Kingdom about 650 years before the events of my novel.
This was used to write an ancestor of the Thussic language. But although some of its characters resemble modern Thussic ones and, like the modern script, were also derived from logograms; the characters in this script were not assigned for the initial sound of the word but for symbolic considerations. For example, the character for /m/ represents soil, which in the language is "angz".
The inventory of 17 signs, divided into two sets of categories (with the 17th being outside of the second grouping) is of religious and philosophical significance: for one thing, it models the Thussic binary division of categories, with an additional odd category always added on: 3, 5, 9, 17, 33 etc. The vowel symbol (which can stand for any of six sounds) represents that Odd principle which is commonly understood as a symbol of the divine (and for which zero, after its adoption, has more recently been adapted by the orthodox church). In the orthodox color wheel this principle is represented by the black rim and spokes. (A modern offshoot sect from the orthodox regards prime numbers as sacred, but that's another story.)
There are other symbolic meanings which I feel like saving for the novel.
The script was meant to be hard to use: "HrrngŁ Chuzho" means "hidden script" in modern Thussaf. In fact, for the most esoteric texts, the vowel character was only used to indicate initial vowels.
(If anyone thinks I should mark this as having mature content because of the fourth character in the second row, let me know.)

Siddham was an indic script descended from the Brahmic script and the ancestor to modern Devanagari. It was used by Japanese buddhism to write sanskrit (and Pali, I guess), and is what you probably get when you see sanskrit written in magical spells and whatnot in anime. In Japanese, it is called bonji.
This is a blackletter-style derivative from Siddham, just because.

edit2: The hexagonal script was constructed to be used with Rinapri during the Age of Coast Temples, and it survives only as the most sacred script with decorationally complex orthography, various writing direction combinations and secret messages opening for those with the Eye. Hexagonal texts cover walls of coast temples and spells are carved onto amulets.
