Tiberoa
Tiberoa is the central country in Endiness, directly connecting each other nation, From North and South Serdio, Mille Seseau (via Illisa Bay), and even he Death Frontier. It is governed by King Zior and his two daughters, Princesses Emille and Lisa. In terms of climate, it is mainly arid desert, though its northern city of Donau has had a successful vegetation project that has brought a great deal flora in the area local to the city. A similar effort has begun around the Capital, Fletz. Tiberoa also technically contains the town known as Home of Giganto on the map, though it is occupied entirely by bandits now and is not in any way governed by Tiberoa, as it is on the other side of the Valley of Corrupted Gravity, and bordering the Death Frontier.
Tiberoa has a culture heavily based around the stars, with particular emphasis on Astrology, which in this universe, is tied with Astronomy as it was in our world, centuries ago. Much of the aesthetics, naming conventions and decorations in Fletz and the Twin Towers are based around the celestial sphere, including the sun, moon, and stars.
Tiberoa has recently had an extreme influx of bandits that have become more bold in both Fletz and Donau. Fletz is also the country that is the most opena bout their divine Moon Object. While both Serdio and mille Seseau are highly secretive about theirs, Tiberoa incorporates it into their open public Coming of Age Ceremony, passed on to the next generation when the heir apparent turns 20. However it is also the only country that we do not learn where its Moon Object is stored.
Tiberoa is the birthplace of Kongol, who was born in the Home of Gigantos.
