They will eventually be human looking chess type characters.
The White Queen has discovered that her Husband the White King has been bumping uglies with the Black Queen. This throws the queen into a high rage, a rampage to end all rampages. She orders her royal guard to attack the Black Queens Castle.
This will follow a traditional Mario type scenario. After the White Queen kills the Black Queen she discovers it was the Red queen, the Blue Queen(etc). Each time the magic scenarios will get more complex.
