Two settlements hold the plains between them. Vanelona is the capital, four centuries of construction stacked on its own older foundations. Wisteria is the second largest, and it is grown rather than built.
Vanelona
A city built on top of itself. Tunnels and forgotten basements run under the newer streets, and the deeper levels give way to masonry nobody living remembers laying. It is the seat of the Spire Caps and the Knights, which makes it the worst place in the world to be caught casting in the open.
Practically: highest vendor density, the most quest givers, and patrols that respond to quick casting fastest.
Wisteria
Not just a tree but a whole city built into and around one, and far larger than its age should allow. During the war people pushed magic past its limits on it, and the result aged it thousands of years in a fraction of the time. Magic runs concentrated here, the wildlife is stranger, and plants grow in ways they do not anywhere else.
Witches cluster around both cities. If you are looking for other players, this is where they are.
