Witcher 3 Themes and Writing Advicd

Hello folks,

I've recently started playing Witcher 3 which led me into the rabbit hole of learning more about the Witcher lore and a greater appreciation towards the worldbuilding and storytelling of the series. It's given me the inspiration I needed to set me off the creative rut that I was in - and make short stories inspired by the Witcher based off my own culture as well as my other neighboring countries.

My question is, what are the themes and maybe other people like about the Witcher that makes in an enjoyable franchise, considering all formats like the games, the books and the comics.

Also, what do you think I should consider when writing so as I can remain as original as possible with my own story?
