This would be a zone that is gained entrance through the wizard's guild that would put the player(s) on a glass marble chess set. Maybe a few secret perks for any non wizards who can find a way to sneak in (maybe a wizard friend or something.)
It would be very interesting if we could some how make NPC scripts which move like their corresponding chess pieces. And it would be cool for each room to be one space on the chess board. For extra points, the board would be on a table, visibly on the map to help with the illusion that you are shrunk down on this table you were just looking at.
Hate to add to the epic to-do list, but couldn't not write this one down to come back to one day.
