Vampires.
Typically, they were monsters who wore as much as they could to block out the sun. However, that's so last century. Basinfall's vampires wore light clothes because staying in enclosed spaces with thick leather clothing is stuffy.
Balding-Man wasn't surprised at their casual appearance. He has explored the world of Tudmang quite well, at least the good part of the continent of Basinfall. He has his fair share of experience, as well as fought many a foe, including the vampires themselves.
What was different from the usual rare vampire he occasionally fought, these guys had levels higher than him although not too far away. As they were simply classified as monsters instead of bosses, he thought he could somehow win against them if he struggled enough.
