In a recent interview of Eurogamer,many information about the settlement have been revealed.
The settlement will be a little village at the beginning,but when we'll make progresses in the story,the settlement will evolve with Eivor.
We can make some activities to get new citizens and also when we return from a mission,we can find some new things.
Also the romances will be important,because we can have a relationship with a girl and date her every time we return from a mission.
There will be also magic drugs to see mythological events and a QG of the Hidden ones.
