The Secret History of the Three Worlds

The Secret History of the Three Worlds is a controversial book claiming to "uncover" the "secret history" of Galhaf, Ufsandakh, and the unknown homeworld of humanity, written in 795 OE.

According to this book's claims, a godlike, but noncorporeal, race exists on Ufsandakh called the yebade (claimed to translate as "wise thinkers" in their own language). This race has sought to create intelligent beings to serve them and spread life and enlightenment throughout the universe. The book claims that the hive-minds were their first attempt at creating a sapient race. After that attempt failed, they tried again, creating the pteranthropans. While the pteranthropans lacked the hive-minds single-minded aggressiveness, they proved too passive for the yebade, who, after long experimenting, discovered a way to bring humans to Galhaf. Humans were the ideal middle ground. They've further directed human development on Galhaf through strategic "possession" of various individuals throughout history, including great military and political leaders and scientists. They've also posed as gods to shape religions.

Supporters of this book point to its allegedly successful prediction of the discovery of Havatrakh. It is true that The Secret History did describe an additional planet beyond the orbit of Ufsahastakh, but critics point out that A) The Secret History described it as Galhaf-like (supporters retort that the description may refer to a moon of Havatrakh, rather than Havatrakh itself), and that B) there had long been speculation about the possible existence of an eleventh planet.

Several rival religions have been founded upon the claims of this book, both collectively referred to as the Trimundial faiths. Both are centered on the belief in the Yebade as godlike beings, and on the rejection of an immortal soul, believing, rather, that only those who find favor with the Yebade will be preserved post-mortem.
