Lyonoya is one of the Eight kingdoms. Its capital city is Chaya. Lyonya borders Tsaia to the west, Pargun (and possibly Kostandan) to the North across the Honnorgat river, Prealíth to the east and the Dwarfmounts to the south (beyond which lies Aarenis).

Lyonya is unique among the known kingdoms in that its rulership is shared between humans and elves. Much of the land is forest, home to an elvenhome kingdom known as the Ladysforest. The ruler of this elven realm co-rules Lyonya together with the human monarch.
