10 Lost Cities The Uncharted Film Could Explore

10. The Kingdom Of Opona

When you hear "lost city", you probably picture thick, impenetrable jungles, towering, snow-capped mountains, or deserts that stretch uninterrupted from horizon to horizon. That's not the case with the Kingdom of Opona.

In Russian folklore, Opona is said to lie at the edge of the flat Earth, where it is only accessible to the most courageous of explorers (i.e. Nathan Drake). A common tale among Russian peasantry, it was believed that the inhabitants of Opona -- also known as the Golden Land or Belovodye -- lived happy, peaceful lives, undisturbed by the state, or by the state's noble, ruling class. Instead, they were presided over by a "White Tsar", who ruled according to ancient, just ideals.

In many ways, northern Russia is among the planet's last frontiers. It is INCREDIBLY sparsely populated, with less than 35 million people in an area almost twice the size of the continental United States (which hosts over 300 million people).

The film could see Holland's Drake traversing the snow-bitten Chersky Mountains, or possibly the vast wilderness of Siberia, which hosts random explosions attributable to underground methane pockets.

It could even tie in the lost Library of the Czars, supposedly created by Ivan the Terrible.
