The Wisdom of The Prophets is a book which purports to contain prophecies for the ler. However, many ler consider it to be of questionable, possibly even non-ler, origin, roughly on a par with The Protocols of The Elders of Zion as far as legitimacy goes. It is based on the theory of serial evolution, and injects a competition between ler and human that is not widely considered to exist.

One of the prophecies mentions "marvels and wonders in the house of the last single generation"; since the ler use base fourteen, this must be read accordingly.
