I was also thinking about the mages in this game. We were told so much about how cool mages are. We see a minotaur who brings bloody sacrifices to his gods and he is a real killing machine, he is as if he is capable of destroying an entire army on his own. But according to the plot, we know that human mages kicked their hairy asses too.
So, how does the MC even think of confronting his sister and mother?! So far, she is only capable of minor mischief.
I thought that this is why the manticore was introduced into the plot. Considering how the MC almost worships her, being an adherent of the old ways of her people (we are kind of hinted that in the current empire everything is already very different), it is quite obvious that they ... will get closer and the manticore will become the MC's support. But is this enough?
And then I thought about shamanism. I really liked how the ritual at the festival, in which the main character can participate, considering it something humiliating and stupid, later turns out to be something much more complicated and she will receive praise from the shaman.
Developing this theme, could the main character start practicing shamanism? It seems to be mentioned in passing that she has an innate predisposition to magic, but she did not go down this path, because she always went against her authoritarian mother.
If the magic that the imperial magicians practice can be imagined as the subordination of reality to one's will. Then shamanism is rather... coexistence. The way shamans interact with spirits is similar to how the main character interacts with the orc tribe, of which she became a part. This is both mutual use and an attempt to get along together, despite the fact that they are very different. Developing this idea, I see a series of quests, where the main character, developing his relationship with the shaman, also interacts with different elemental spirits (oh, how much fun you can come up with here, if you know what I mean), for example. It would be strange if she eventually became a real shaman. But having acquired, for example, the ability to strengthen her armor (spirit of the earth) and enchant weapons with fire (spirit of fire), or even the ability to temporarily acquire protection from elemental damage, she would have become a pretty good anti-mage. And the ability to beat up your sister would have looked much more realistic. Even in today's reality, where fights are so miserable that they just exist. You can implement a really cool scene. Where the main character cuts up his sister's defenders, receiving a ton of elemental damage from her every turn, pressing elemental protection in time, and finally gets through to her in hand-to-hand combat. And then... well, it would be weird to kill her right away, wouldn't it? :3
