Hi Watcher! 

If you are looking for a pokemon site, I recommend looking at hoenn! It isn't a medieval site but it's very chill for a better lack of words! As long you stick to the rules and guidelines, you can probably do whatever you would like. The site's is a bit on the larger side in terms of members which can be intimidating, but the community is one of the most welcoming ones I have ever experienced for Rp! The site is very active, and it's ran by a very dependable staff team who do their best to make sure everyone is having a good time, and they release frequent events for the community! Members are also able to do their own events, so most of the time theres a lot of stuff you can do. 

Anyways I hope you consider looking, and if it isn't for you, best of luck for you to find what your looking for!!
