Here is a lot of useful modular stuff (geometries are decimated) :

1. Walls, floors, battlements, animated doors...
2. Chests, table and bench,bottles and glass, ornamental (or not ?) swords and shields....
3. A landscape material and a customizable commented post-process.

Some ideas for your project, I hope 😋
