So for a while most of us believed that the tower and the last city were located somewhere in South America. Well, we were wrong. How? Well it says so right in the lore. According to this [url=https://www.bungie.net/en/Armory/Detail?type=item&item=4006760092&itemname=Five%20Mile%20Mark]titan mark[/url], after the battle of six fronts, [url=https://www.bungie.net/en/Armory/Detail?type=item&item=4006760093&itemname=Mark%20of%20the%20Sortie]two groups[/url] of Titans (Jagi and Radegast) pushed back the fallen in a five mile radius from the city. Now who is Jagi? Well, according to[url=https://www.bungie.net/en/Armory/Detail?type=item&item=4006760094&itemname=Mark%20of%20Jagi%27s%20Host]this Mark[/url] Jagi continued pushing back the fallen for as far as he could go, which was the Caspian Sea. So what does this mean? It means that the location of the tower is around the Caspian Sea. Probably in this [url=https://www.google.com/imgres?imgurl=https://upload.wikimedia.org/wikipedia/commons/thumb/e/e3/Caucasus_mountain_range_map-fr.svg/2000px-Caucasus_mountain_range_map-fr.svg.png&imgrefurl=https://en.wikipedia.org/wiki/Caucasus&h=1555&w=2000&tbnid=OBdcWyoyWCkXVM:&docid=6eajjLWF6ewXAM&hl=en-us&ei=r3J0VsjELov_-AGk05uYDw&tbm=isch&client=safari&ved=0ahUKEwiI2OnXpebJAhWLPz4KHaTpBvMQMwggKAAwAA]mountain range[/url]. It also seems that our reclamation with the world is very close to the tower's locations. There is no in game area outside of Europe. What does this mean for the future? As the guardians continue to push out, we will encounter more areas of earth. Africa, Asia, the Americas. Soon enough we'll see them all.
