Saleen and Lex looked at the tens of thousands of notes, both unwilling to give them away. These notes from the mages had a large amount of information on magic beasts in them and described more than one hundred thousand magic formulae.
The Figaro formula was the basic theory behind all magic. However, that did not mean that by learning the Figaro formula, one did not need to learn the others. There were over ten thousand basic sequences in the Figaro formula alone, and they were even more complicated than the changes in the stars.
A mage could study for all of their life and still not learn all of the formulae, much less create so many of them. However, all of the magic notes in this hall carried related information, and if they were separated, their value would drop steeply. Seeing that Lex was not saying a word, Saleen knew that she was unwilling to give them up.
