I've just finished the research to be able to upgrade my main hall to level 34 for the third time.
I really like the task of being "forced" to break out out of old city structures, that's when puzzleing, the strongest weapon of Elvenar, comes into play!
2 further cities are follwing this one, what means apart from my both biggest cities that are both heading towards chapter 18, I will soon have 3 further cities starting with chapter 16 and of course some other, smaller cities too.
I have meanwhile got to know a lot of humans and elves who were or even still are running multiple cities, but it seems like there weren't that much who tried to bring multi-worlding to next level like I am trying to.
Maybe I will be the most "experienced" multi-worlder in Elvenar one day.
Honestly I am still really curious if the grind will be able to bring me down one day.
