One Becomes Many is a book given to Lyrthindor, which convinced him to split his body and soul into multiple creatures under the auspices of becoming strong enough to defeat much larger creatures. Yet its true purpose is to have him evade an Orthon.
This book is redolent with the enticing smell of paper and ink.

Text
In each of us is more than what we are;
Parts and multitudes that form our thoughts, desires, nature itself.
Manifold are the creatures inside you - and what you can become when you speak my words is all your parts made manifest.
Your weakness can become strength if it is made legion: quaking hearts can find courage in their numbers, the lowliest vermin can humble a 
goliath if they stand as an army, and a ruin can become a kingdom for one soul made many.
Speak Itori mustag thrice.
Become your finest self - all of them
Raphael.
