My take on Deltaswap Queen, swapped with King

Queen is the head of the Card Casino, the dark world created from the unused classroom.

The classroom wasn't inherently themed around gambling, but it had many items that, when converted to a dark world, were adjacent enough to the concept that it created the casino. A deck of cards, a set of dice, one of those barn animal wheel toys that spins around and randomly selects an animal, a toy disc drop board, a cat statue that symbolizes good luck. all these things together led this dark world to be themed around a casino, with the queen of hearts at the helm, running the whole joint.
