The Canon of Pyrrho
Pyrrho’s philosophies were instrumental in the construction of the modern school of illusion. None of his original written works survive in modern Toril, but his ideas and doctrines were recorded by sundry of his pupils. He came to the conclusion that reality was ephemeral in nature, not absolute. More importantly to the school of illusion, neither was falsehood absolute and there was no inner truth or certainty to the nature of things.
The Canon of Pyrrho contains what Nimbral scholars consider to be some of his most important axioms and fundamentals. Modern editions are usually written in Ruathlek, the language used by Nimbral mages, but there are a few Halruuan versions still in circulation. One obsolete, poor translation exists in the Common tongue. Scattered throughout the texts are numerous magical terms from ancient Netheril; Pyrrho was a scholar from that era, but the text of the original works that form the Canon of Pyrrho no longer exist in Netherese.
Readers unfamiliar with the Netherese language can begin learning it with the Canon of Pyrrho. Within it there are large blocks of Netherese text side by side with their translation, which makes the work a favorite of Wizards attempting to learn more of the ancient civilization. This work can be used by someone attempting to learn the language of Netheril and counts for up to one quarter of the research materials needed.
The Canon of Pyrrho grants DC 17 ability checks to Lore Arcana rolls that deal primarily with illusion. It grants DC 14 Arcana checks to answer questions about Netherese magical philosophy.
