A good read, all in all. I find myself wistfully going back to The Great Tournament and Lords of Aswick as I read through this work, with the classic medieval fantasy twist on it.
I liked the lore dump, and find the Sorusian Empire comparable to the Roman one.
The story was immersive enough and flowed well, with the narration being crispy and to the point without unnecessary flourishes.
I would suggest thinking about making a map of the world for easier player reference and a save system in the future demo (it’s actually one of the easier things to get done in Choicescript, God help us)
Keep up the good work, the magickal twist on the entire story seems interesting enough and stands it apart from your normal medieval fantasy IFs. Ave 
Edit - I saw you you were wondering about how to implement save slots
