Chessboard Land is a land on the Isle of Wonders ruled by two chess Queens. The queens live in the Castle of Chessboard Land. The chess pieces of the land have vowed to never let humans into their land. Alexander tried to convince them to let others into the kingdom. The queens finally agreed to a grand opening of the kingdom. This didn't work out however, as the queens bicker too much between themselves. They again changed their minds, made everyone leave and closed the gates to their realm, locking it with a golden lock. Not only did they intend to keep people out they took it further keeping people from looking in.
Graham acquired the key, got past the lock, and was told to leave, that his kind would not be allowed into the kingdom ever. Graham later acquired a cloak of invisibility, and snuck past the guards into the kingdom.
