On the fort I'm currently playing, Workedsharks, our first migrant wave was 10 dwarves.
We didn't have any more migrants for like 3 years.
We just got a wave of migrants that singlehandedly raised our population from 17 to 51.
I had just accepted that we weren't getting any new dwarves anytime soon and was NOT prepared. Time to haul ass and carve out bedrooms😭
