Book of Ages

The Book of Ages is an ancient book that magically records the accounts of history as they unfold. 
Whoever writes in the book effectively holds the power to change the course of history. 
After the last of the eight demon portals was sealed, the Demon Sorcerers reluctantly agreed to use the book to escape from the Netherworld, hesitant of its power, as misusing it could alter the very fabric of reality.
== Appearance ==
It is a gigantic book with writing throughtout all history.
== Powers & Abilities ==
he book's main function seems to be that it records history, though the enchantments allow anyone who rewrites it to change history to their whim. 
There seems to be no limit to what changes can be made, as Jade was able to write that the J-Team inexplicably gained superpowers and it happened. 
Uncle even gained the items and power needed to banish several demons simultaneously when Jade wrote that he did so. 
The main defense against the book's power is to obtain a piece of one of the book's pages that details one's own history. 
History still changes around them, but they remember the unaltered version of the past, and can reverse the revision by returning the part of the book that they removed.
