According to the autobiography of the tomb's master, he was originally surnamed Han, with a single character given name, Yuan.
This Tomb Master named Han Yuan was not a native of Yang Kingdom but hailed from Di Country, born into a sect known as Thousand Spirit Sect.
The Thousand Spirit Sect was famous in Di Country for its Insect Expelling Technique, claiming to possess a thousand types of spiritual insects.
Although the Thousand Spirit Sect had a considerable reputation in Di Country, it had never produced a Nascent Soul Stage cultivator. It had always been a medium-sized sect, much like the Sanjue Sect.
Han Yuan was originally the Vice Sect Leader of the Thousand Spirit Sect and was expected to take over the leadership in the future.
However, his obsession with collecting the various strange and exotic insects recorded in the sect's classics, and his passion for breeding them, led him to violate the sect's taboos.
