This spell is similar to mental ledger in that it enables the wizard to record information in some unused portion of the wizard's brain, and then gives the wizard the ability to read the information at a later date as if they were reading it in their own hands.
This spell actually will allow the wizard to hold as many spells as he knows and any that the wizard might learn in the future. In fact, any spells that are stored in the wizard's brain through the use of the spell will remain there essentially forever available for recall when necessary. This spell also allows the wizard to record information other than spells in this "storage area". The wizard can store the entire contents of any book that he reads and can access the book at any time in the future just like mental note. To add more information after the spell is cast requires that the wizard cast the spell again at the time that they wish to add more information.
The material components for this spell, the first time it is cast, are a specially prepared lead crystal which has been enchanted to absorb magical energies. The value of this item can be no less than 50,000 gp. To add more information in subsequent castings, the wizard would require a pure lead crystal of 5000 gp (as in mental ledger).
This spell is highly useful for wizards on the go who want all their spells and library without having to carry it around for themselves.
The casting time depends on what is being stored. It takes one hour per spell level per spell memorised, and it takes the time it takes the wizard to read a book to store a book (the wizard is allowed to take short breaks and sleep if there is a large amount of information being memorised).
