Rucien-Xan was a hidden elven realm allegedly located somewhere in the Chondalwood. Supposedly, it contained only one city, also called Rucien-Xan that served as the capital for both it and the nearby realm of Nikerymath.

No explorer or adventurer has ever found Rucien-Xan, though stories exist mentioning it that date back to the time when Jhaamdath was founded.

The moonstars did, however, have an agent in Rucien-Xan, though obviously this was a closely guarded secret, as was most of the moonstars' activity. Nuvian Eyes-Ashen was their regional agent for the Vilhon Reach and Shining Plains regions.[as of when?]
