Please forgive me if my english sounds a little bit strange from time to time, but I haven't had too much practice at translating text from german to english in the recent past^^ I don't know how regularly I will post here, but I will try to go through the whole german series (which isn't finished btw) if you are interested.
Don't worry this will not contain any spoilers regarding Forgotten Stories, as the cells I'm going to show were agreed by the devs
If someone wants to take a look at the location for themselves, I am going to post the Cell-IDs so you can access them by console. But as I cannot guarantee you that visiting those locations per console won't have any effect on your savegame, I would advise you to do that directly from the main menu. Furthermore it is possible, that some cells might get removed from the game with a future update (I tested everything with 220.127.116.11)
Part 1: "It starts with the startcell"
One of the first rooms I discovered is an old startcell, that was once either used for testing or meant to be a part of the prologue.
You start in a cave in front of a door that doesn't lead anywhere and you get immediately thrown into character creation.
- [+] Spoiler for the Mainquest
- (roughly translated from german) "Those were children from the civilisation after the Cleansing. They were playing in the ruin and found the notes of the prophet. Then the story of Enderal began and at the end of the game, you would see them again. The kids would leave the cave and you could see the civilisation that had developed."
