- This is a 10-volume series of books that Xio found in the [[Library of Oghma]]. They talk about the structure of language and how things are named, including a list of the true names of things that would give the wielder power over them. - Xio unfortunately had to abandon them in a cart near the [[Round Rump]], along with [[Ka'ira]]'s armor. - [[Hill]] managed to take the first volume for Xio before he met up with the rest of the crew. - The words of power are in [[ttrpgs/Order of the Wandering Mind/Supernal (language)]] and [[ttrpgs/Order of the Wandering Mind/Abyssal (language)]], languages that are difficult to pronounce for humans. - Words of power are used as true names for creatures, places, and things. The first volume talks about true names for creatures. - Requires a feat in true naming to fully understand.
