Yes, there are doubts. On one hand, it’s quite possible that there will be two storylines (maybe three). The first could be a war between humans and demons, perhaps with the undead involved, or the undead fighting against neutral mages (this is a possible third storyline). The second could be about orcs conquering territory belonging to a new faction. But on the other hand, it’s mentioned that there are five members of one family, and the question arises: what the hell would a member of the royal family be doing with orcs and, presumably, nagas? Could it be that the mages took the king’s son and turned him into an orc, and he became the leader of those very orcs and planned an escape? I don’t know how a descendant of the royal family could end up with the nagas. Mages and elves would seem more preferable and logical here.
