Even I'm not 100 % sure but I think since the time period for which the sun sets there is pretty long compared to the normal cycle, it will be quite convenient for the werewolves who want to stay in human form I guess. And yeah,the climate is suitable for furry wolves and I think the supernatural wolf creatures originated from there and dispersed all over the world and Bexan going back there is him kinda reaching back to his roots on top of staying in human form for a longer period. Again, this is only my opinion,so we will have to wait for the author's plot advancement to find out the truth.

Okay back up. I’m a little lost. Lol. How are they going to verify these Serbian wolves are actual wolves if the sun “never shines”. They’d just look like regular people right? So then is the importance of Serbia that It allows them to get rid of their wolf side??? Because they don’t have to worry about the sun morphing them into animals???
