Nera

Nera is a 116 kilometre river in Italy flows almost entirely in Umbria. It is a tributary of the Tiber river.

History[]

During the early 16th century, Cesare Borgia had established facilities in the valley of the river which were used to produce large numbers of Flying Machines. They were subsequently destroyed by the Assassin Ezio Auditore da Firenze, who stole one of the flying machines and used it to destroy the factories.^[1]
