Theme: Chess
The user would enter a psudo-medieval castle and inside the player would walk onto a small segment of a chess board and in order to proceed, the player must push a piece (or multiple pieces) in order to check the opposing king. Success means that they proceed without battling a trainer, failure would result in a trainer battle and then the path would be opened up.
Upon completing 4 or 5 of these mini chess boards you'll approach the leader's room which would be in the castle's throne room.
