You MUST be a colour
I move the black light piece forwards one place.
"Checkmate," I say triumphantly. The board disappears in a flash and I look across the table at my sister, Ivory. Together we are the two Light princesses, one white, one black. She glares at me.
"It's not my fault I'm better at chess than you," I say, getting up.
"Chess is boring. Come-," she says, interrupted by a voice from the doorway.
"Could both Princesses please come down to the main hall for a meeting," says the messenger, dressed in yellow, the third highest colour.
"Oh fine," says Ivory irritably. We go down the staircase and push open the doors.
