Each of the Aethyrs has an angel associated with and residing within it.
The Aethyrs ( アイティエール, Aitiēru ?) are 30 planes of the world's spiritual territory, which play a major role in Enochian magic. The usage of Enochian magic involving the Aethyrs and the Secret Calls has been noted to fall within the Aeon of Horus. A set of invocations, known as 'calls' and often referred to as the Secret Calls, are used to access the powers and angels of the Tablets or the Aethyrs. In Enochian traditions, a diagram of the world's spiritual territories depicts a square at the center, comprised of the four tablets/watchtowers contained within a tablet of union, surrounded by 30 concentric circles representing the Aethyrs, with the 30th being the innermost and the 1st being the outermost. Two keys parts of the Enochian magical system are the Elemental Tablets and the Aethyrs. Enochian glyphs often have English letter equivalents, however while some of their names are pronounced the same, many are pronounced differently. The Enochian language has its own alphabet, with several different forms of script.
The system of Enochian Magic ( エノク魔術, Enoku Majutsu ?) is based around Enochian, said to be an ancient angelic language, and often involves the invocation of such beings.
