Valnerina
Valnerina (English: The Valley of River Nera) was a location in the Italian state of Umbria. During the early 1500s, the valley was used by Cesare Borgia to produce large numbers of Flying Machines designed by Leonardo da Vinci. These machines were each equipped with a single cannon and were intended for use in Cesare's conquest of Italy.[1]
The production facilities were destroyed by the Assassin Ezio Auditore da Firenze, who stole one of the bombers and used them to destroy the factories.

Valnerina
A valley formed by the Italian Nera in the mountains of Umbria, the Valnerina was known for its winding roads and steep narrow passes. It was a particularly challenging landscape to navigate.[1]

Nera
A tributary of the Tevere (Tiber), this 116 kilometre river flows almost entirely in Umbria, Italy. I might also add it has some spectacular fly fishing which I'll likely be taking advantage of if we survive this ordeal.
