There is a series of tomes called the Angelic Chronicle. One particular tome, the Nephilimic Order, is a book written entirely of angelic beings. It is the purest text in existence. It remains entirely untarnished and pristine. It cannot be damaged, destroyed, corrupted or even remotely touched by anything evil. The presence of this book alone banishes demons for at least 1,000 miles in all directions.
It contains secrets, rituals and methods of summoning that could bring forth some of the most powerful creatures down to walk among humans. However, the reason no one has likely done this is because the exposure to these creatures would likely incinerate humans and or destroy much of life as we know it. Similarly to demons, higher up angels and beings omit an aura that few can withstand being exposed to for an extended period of time.
Due to this, the book does shed light on instructions to create a piece. It is called Seraphic Light. It is an item that allows the holder to summon and be in the presence of angelic beings. It also shows that, while using this item and being in the presence of these beings, the wearer will experience change in themselves over time. They will absorb the angelic energy, become pure and essentially ascend over time.
If you do not want to become an angelic being walking on Earth, please let us know so we can remove that ability for you before we send the piece.
