[@rezay] I like that migration, I see no problem with how much they have explored. If anyone, nomads are certainly the ones who would know about large swathes of land from the beginning :D

As for population, I'm still deciding if it should be an actual data or just handwave it. So yeah, that one is up in the air for now. Not that it's too relevant. I imagine populations for most races are about 100 at max, no more.
