Arden Vale:
An Eld Tree on a field of grey.

The tall and narrow Elven banner denotes the height of the Eld Tree (a tree somewhat like a sequoia, but with leaves instead of needles and reaching heights of a thousand feet). This particular banner represents the Lone Eld Tree growing just inside the hidden southern entrance of Arden Vale. The field of grey signifies not only the twilight shed by these trees when Elvenkind is near, but also the general neutrality of Elves in the internal affairs of mankind and the folk of Fey. It is said that when the Lone Eld Tree is no more, no longer will Elves dwell in Arden Vale.

Kistan:
A maroon field.

(To match the sails of the ships of the Rovers of Kistan)

The only authority the Rovers of Kistan recognize is a council of ships' captains. Hence, the Kistanian flag itself bears no device. However, each ship's captain is free to add his own ship's symbol to the maroon field.

Jûng:
A red star on a yellow field.

This is the flag of the Mogul—the Warlord of Warlords—of Jûng. There are many warlords in Jûng, each with his (or her) own feifdom; in general, each of these warlords has a flag of his own, the design of which represents that warlord. Yet in spite of their own internal warfare to gain the territory of another, they occasionally unite under a single Mogul, one who has come to power through warfare within Jûng, or (rarely) has been elected by the other warlords, or more likely at the behest of the priests of the Jìdu Shàngdi (another name for Gyphon). The Mogul always uses this flag, though he (or she) retains his own flag as well.
