They never had contact ? Like when ? People travelling most of the globe way before British figured out basic stuff.
Ancient sumeria, Egypt, Assyrians and Indians had concepts like crowns. Also if a civilization did something cool, others usually copied it under 200 years.
Not a historian, so grain of salt.
I don't understand the plot, can you please explain?
The goober. The countries want it to control them. Ethan wants it so we can destroy the entity. Why does Gabriel(the entity) want it ?
Why can't the entity nuke Rome when two parts of the key are on Rome(or Venice) and be done with it.
Ona side note,am all knowing entity can't get to its own source code or recreate it ? I have a feeling that the entity wants Ethan to get the key for some unknown reason.
