The Yan Kingdom is located at the border between the Eastern Desolation Central Domain and Southern Domain, separated from the Central Domain by a wide Black Water River where a Flood Dragon lies dormant.
To the south, it is divided from other small cultivation countries of the Southern Domain by the Purple Vine Mountain Range.
To the east lies the Wei Kingdom, a large cultivation country in the Southern Domain,
while the northwest borders the Ten Thousand Poison Swamp where the Ten Thousand Demon Country's Nanling, the Central State in the cultivation Dynasty, and the Eastern Desolation intersect.
Within the Ten Thousand Poison Swamp, there are numerous unconventional cultivation forces, including the infamous Five Poison Sect, which wields poison that makes multiple cultivation dynasties in the Central State shudder.
Celestial Secret City uses puppet sea tactics to prevent the Demon Race of Nanling from easily traversing the swamp.
