1.2 If we consider the orc tribe as creatures that are half-human and half-animal, then minotaurs fit into their atmosphere.
2. There's a complete mess with the mages. I've searched almost all of mythology and still haven't found anything that could be incorporated. I have one idea, and that's the Sphinx, but I think Rakshasa will be enough. I'm still not sure about the dancers. I'll keep thinking about what to do with this city.
3. The guards have spears as weapons (if I'm not mistaken about the weapon name), and the swordsmen have swords :D. I also had problems with the humans. I've never liked playing as them, so I don't know who to add to their ranks.
If something needs to be clarified, feel free to ask. For now, I've created an analogy; then, I want to draw each unit and write down their strengths, but first, I need to be 100% sure that the work on this will be finished and I can move on to the next one.
