I just wanted to share some pictures of the castle I've been working on in one of my modded Minecraft worlds. I mostly proud of this one because I haven't used things like litematica and I haven't used cheats for anything relating to the castle (I have a real problem using cheats in my survival worlds, so this is a great step for me). I have been playing in peaceful but the point of this world is to be non-stressful and creative while still being a challenge. I'm currently unable to upload pictures directly so I will post links to the images.
I play "Peaceful hunger" I turn off all the bad mobs mainly -you can do this when generating a new world for a single player or in your server.properties with "spawn-monsters=false"
