What really happened to Tesla in Colorado
The witches wanted to summon an ancient god from outer space named Cthulhu to take over the world. The witches hoped to become powerful and help Cthulhu dominate everyone on the planet. Alice and her friends watched the witches cast a spell that made Cthulhu appear.
But Cthulhu couldn't take over the world because he looked like a man, only with green skin, tentacles, and red eyes. To take over the world, Cthulhu had to become big and mighty. The three witches would have to sacrifice Tesla and cast another spell.
