This is the old version of The Princess And Her Warmonger, and it does contain some spoilers to the current version, though not much. This isn't considered cannon as, not only are there quite the amount of grammar mistakes but the information given isn't constant throughout the story. 

However, the biggest change will be to the entire endless war. Now, practically no one in Nostalisk is disgusted with the idea of war and will view war as the best solution. This will change slightly for the Kingdom Faction since they left the Great Wars. The next big change will be for Marrie and her entire introduction. Her accent will still be the same and she will follow the same path but now her character will be more developed and, yes, the invasion of the Mackaroles shall be majorly updated.

That's all! Hope ya enjoy the old stuff and the new stuff!
