Reppaba (Pekorovan: Ropoa Boa; Triluin: Rapuvui) is the largest city on the River Peko, and one of the most important cities on the eastern shores of the Lovi Sea. Founded by the Pekorova in ancient times as a trading center and refuge against the raids of the nearby Nahsjad, it grew quietly prosperous through trade with the Empire of the Trilui. Conquered by that maritime empire and made into the provincial capital of the Triluin Peko colony, it served as an administrative center before falling to Siran Maninists. Adopted as the southern capital of the Siran Roshate, it remained important through the rise and fall of the Khivani Roshate, eventually becoming one of the principal cities of the Dual Empire.
Reppaba is still a principal port for the Peko valley in the present day, but the valley's exports have been reduced mostly to luxury goods -- for the most part, Reppaba instead imports from elsewhere.
As the largest eastern city in the Dual Empire, Reppaba was chosen by Khatai I as the site of the largest Eastern Aitahist temple to date -- a beautiful construction of white stone, imported glass, and red cloth hangings. It remains partly unfinished until recently, testament to the impact of the War of the Empty Throne on the region, but its central chamber is one of the largest buildings east of the Lovi Sea. It was finally completed by the Farubaida o Caroha, which is organizing Reppaba as a capital of a sixth federate.
