EDZ is placed along the border of Switzerland and Austria (and Liechtenstein). As biist said, the details match up almost perfectly with eastern Switzerland. Plus, there's plenty of salt deposits there. The signs are all in German, and street signs say 'Graubunden' (one of Switzerland's cantons) and 'Zervreilahorn' (A mountain in Switzerland). Now I have another theory - that of where the Last City is. In the first mission of Destiny 2, 'Exodus', the player leaves the last city and arrives at the farm in the EDZ. To do this, the player has to cross some very steep and snowy mountains. To 1. be within walking distance of the EDZ (Switzerland) and 2. remain steep and snowy year-round these mountains would [i]have[/i] to be the Alps. There is a mountain in this mission that looks strikingly like the Matterhorn. This mountain is directly north of the Last City. Now, what major city in Europe is directly south of the Matterhorn? It's Turin. Milan is also nearby, so depending on perspective it could be Milan too - but in my opinion it is most likely Turin, because its angle lines up much better with the Matterhorn in 'Exodus' As an added bonus, the Last City seems to be built on an extremely large valley/basin, and there are mountains closer to one side of it than the mountains near the other. This lines up perfectly with the location of Turin (Milan too, but again, more Turin). - the Alps and hill formations in Italy near Turin form an environment very similar to that of The Last City. Now, let's continue tracing the steps of the guardian as he/she climbs through the Alps toward the EDZ. After seeing the Matterhorn and the last city, the trail makes a turn and they start heading north. There is a confluence of two rivers or streams - at either the town of Zermatt (or Stalden further down the river) or Les Hauderes. However, the view of Les Hauderes would be obstructed by more mountains. Plus, Zermatt (or Stalden) lies along the route towards the EDZ. The player starts heading down the slope, down into the valley. They fall, and are picked up by Hawthorne. This would take place somewhere in the river valley near Zermatt. The player is airlifted to the farm, and then is dropped off at the shard in a place called The Blackened Forest. Based on the location of the EDZ, that name is no coincidence - the shard probably landed somewhere in the eastern part of the Black Forest, Germany. The farm, based on its flatter surroundings, lake and mountains above it, and proximity to the EDZ, it's probably somewhere on the northeastern (German) shore of Lake Constance. Which, by the way, is dotted with many picturesque farms. So, to sum it up: -EDZ is eastern Switzerland -The Farm is near Lake Constance -The Last City is Turin
