After dinner we go to the Forbidden Forest waiting for the first flash of lightning. We sit in our little circle, waiting for sundown to repeat the last of our incantations. It takes hours for the first flash to light the sky. The magic around us magnifies, we quickly turn towards our hidden potions. The potion has turned blood-red, I uncork it and look around to the others. We nod toward each other and swallow the awful looking and tasting potion.
