In the early 9th century Cambodia, the figure known as Serey Sayavong (born Kasikor Srae) with Sino-Khmer heritage, emerged from the rice farms of Chenla to become a pivotal Master and Mentor of the Hidden Ones, dedicated to the unification of the Khmer Empire under Jayavarman II. Serey Sayavong was known for his "no-nonsense" persona and a belief in absolute precision, often described as a man who "never makes mistakes". His speeches were noted for being loud and fast-paced, reflecting a "fast learner" mindset that he expected his students to emulate. He was transformed from a peasant to a strict, uncompromising leader who viewed the Hidden Ones as the ultimate protectors against the global shadow war waged by the Order of the Ancients, which suggests Angkor was a rumored location for an Isu temple housing a Piece of Eden, known as the Star Stone, which became a primary focus for both the Hidden Ones and the Order of the Ancients. Founded originally by Bayek of Siwa in Egypt and Amunet in Rome to protect the free will of the people, the Hidden Ones in Cambodia, under Serey, adapted these principles to the unique agricultural and spiritual needs of the Khmer people. Under Serey, the Hidden Ones were deeply integrated with Khmer agriculture.
