The Buzhan Clan is one of the most ancient lineages in the Nine Worlds. Some people believe, that it was created by Immortal Emperor Bu Zhan during the Ancient Ming Era, but in fact it already existed for a long time before he was even born. The Buzhan Clan exists at least since the Desolate Era and is even older than the Gu Chun's Four Branches (the first Imperial Lineage in history).
Despite of its ancient heritage, the Buzhan Clan was never famous. Outside of Immortal Emperor Bu Zhan's generation, the Clan had always acted in a very low-key manner. Some people guessed that this had something to do with their origin.
