Six Serpents game - It was the year 990 AD. Salazar, one of the founders of the School of Witchcraft and Wizardry was contemplating taking over the school from his fellow founders. He thought they were too liberal and was upset they were allowing muggles, which are humans with no powers, into the school. Therefore, he invented a curse known as the Curse of the Six Serpents. If you enacted this evil curse, it produced a gigantic field that covered the entire school. It caused anyone inside the school to have to obey the caster, no matter how strong their witchcraft or wizard powers were.
