The Withering Light

Unlike many other Astral Realms, The Vessel of the Holy Light is unsuitable for any sort of life or the ability to host anything other than pure light energy, and on purpose, its used to give Mortals who worship Zavs'Hooran a taste of his power. Its a void of Light and anything that tries to interact with it burns away in his realm.

Light

Forged by a Dragon-Lord, the first plane in existance to be forged and designed by a non-celestial/Titan sourse and only one of two to exist, the other being the Pantheon.   After the Fall of the Scarlet Hall in the Mortal Realm, the amount of magic in the Veil had become less and less with the main magic users being the Dragon-Lords, Luna's creations, and the few mortal bloodlines affected by the Well of Creation and still alive. So Zav'hooran in an attempt to become a god for more power to conquer the Archeon and did such thing, by manipulating the other living Dragon-Lords, he sew lines of betrayal to them and sewn lies to make them fight eachother and kill them when they weakened themselves, gaining their power and tore open a completely new Celestial Realm with great might and power he created one of pure light by infusing his soul(s) to it and, while initially it contained the elements of Light, water, fire, and such- it very quickly got all purified by the Light, which given enough time destroys anything that isn't it.   While his initial idea was to force humans to obey him using this, it was made a lot easier when people started coming asking him for help and people already rather liking the Dragon-Lord for his assistance against the Titans so he already had gathered a rather large following to him. His prideful nature was getting to him as the worship he was given kept fueling his ego and caused the first use of his realm to be gifted to his most loyal of worshippers,   Little did he or his followers know at the time is that his power takes parts of you permenantly, though at such small amounts is not noticable in small amounts.... However for prolonged peroids of times such as hundreds of years- may have devestating effects from your body slowly withering away to just death with the primary case itself being Zav'Hooran himself. Withering and unable to fly anymore.
