Every good action figure fantasy world needs a place for adventurers to blow off steam, drink some ale and start some brawls. Here I used modular pieces in a bookcase to create the atmosphere desired. Tea lights and mood light also helps.
When doing playsets/dios/scenes I've learned over the years that modular pieces that can be taken apart and stowed easily make the most sense for my style and available space. In so doing, I can also rearrange into various alternate tavern builds as well.
