War of Whispers Castle Topper

I like using verrum's castle in War of Whispers.  It has a space to put a cube on the top to mark off ownership of the castle.  Issue is, not all spaces have cube in them (some home territory starts off empty) and makes it really hard to quickly assess castle counts for each empire.

Thus, I made a simple topper to show ownership and allow ease of calculation.

You really only need to print out 8 or 9 of them.  I have yet seen a game where one power has more than 7 castles at the end.
