it's a joke, varna is our rival town (i am from dobrich :) ).
but generally, you find darker people all around bulgaria, it's quite clear the population is mixed with both gypsies and turks. you've got your fair skinned bulgarians with blue eyes, then you've got people that straight up have latino skin color. maybe somewhere between 10 and 20% are really swarthy it's just a byproduct of living in the balkans i guess. i have blue eyes so hopefully i'll be safe when the nazis comeback
