The SoulBound series is pretty clean - there's action and fighting and some creepy imagery and monsters, but it doesn't linger on gore and there's no nudity or sex scenes.
It's within the bounds of The Princess Bride, Lord of the Rings, or Chronicles of Narnia, so if you're comfortable with those, SoulBound should be fine as well.
I think it's a greater challenge to write a clean, kid-friendly fantasy series, but it's well worth it and produces a more engaging and thought-through story that can be shared with a greater variety of people.
Besides, my study doesn't have doors and my kids tend to drop in while I work. That tends to make me aware of what they might pick up from what they see on my screen. Lots of things may happen, but it's how we deal with them that matters, so I won't hide reality from them but I will focus on what can be done about it.
I hope that answers all the potential facets of your question!
