The first Unending Tomes were said to have been crafted by a dragon in the service of a great emperor. Each of these books has a unique appearance, and hold an infinite number of pages for spellcasters to inscribe spells upon.
Any wizard who prepares spells from an Unending Tome, which potentially holds libraries worth of arcane knowledge, may prepare bonus spells as if her Intelligence were 6 points higher. This is not an actual bonus to Intelligence and grants the user no additional benefit. The original Unending Tome contains all sorcerer/wizard spells (save for those of the schools of Enchantment and Illusion)—at the GM’s discretion, it can certainly hold more spells.
A special 9th-level spell must be designed that exists only to destroy the specific and particular Unending Tome into which it is inscribed. This spell, which has numerous expensive and rare material components, must then be cast on the Unending Tome by its owner.
