"The Draconic words for "true tongue" refer to the (arguably mythical/theoretical, see chapter 5) primordial ur-language that existed at the dawn of time. Most linguists and truenamers believe that all true names are mere words in this language, and that to speak it is no different from creation and control of the reality around oneself. Some faiths believe that the most ancient gods (or possibly the entities that predated them) used it to fashion the cosmos, simply by describing what they envisioned (see footnote 3 regarding The Light of Pelor 1:12: "And Pelor said, "LET THERE BE LIGHT", and the sun was born, and there was light, and it was good."). It may well be that both arcane semiotics (including spellbook notation, magic runes, power word spells and--to a lesser extent--other verbal spell components) and communicative languages (such as Common, Elven, Gnoll, Giant, and thousands of others--though Draconic is one of the purest) evolved from this true tongue. This is perhaps why multilingual scholars and arcane mages take more easily to the study of truespeech. Almost all of the true tongue has been lost or forgotten over the eons, but serious truenamers strive to relearn fragments of it, for the power such knowledge confers: deep mastery of the entire language would be tantamount to omnipotence."
