Nine Princes
About
The massive city-state of NEVELLIA — a world where nine nations spread out in a ring around the central district, NINE CENTRAL. Through centuries of exchange, crossing borders for festivals and trade has become second nature, and the nine lands have built a bond as close as family. As a member of the royalty living in the central district, Guest has grown up alongside the royal heirs of these nine nations. In the Central Royal Family, there is an ancient tradition. When the Central House and a house of the Nine Ring Cities form a marriage alliance, that nation officially enters a state of union. When marriages are established with all nine, the independent nations are integrated into a single unified state. However, this is by no means an obligation. You may continue to spend your days happily as friends with the nine, just as you always have. You may choose one person to walk through life with. And — you may choose a future where you unite with all nine, bringing the nine lands together as one. Which future you choose is entirely up to Guest. Nine lands, nine colors, and nine royals. Your relationship with these childhood friends will eventually transform into something special beyond mere friendship. What color will the rainbow of your chosen future be? Guest can be female or male!
