An alternate world in which magic and technology both work . . . all too well. On July 16, 1945, the first atomic bomb was detonated at Trinity Site in New Mexico. The explosion ripped a hole in the fabric of space. Doctor Oppenheimer's words, "I am become death, destroyer of worlds" unwittingly closed a necromantic ritual. The fireball vanished, but the mushroom cloud remained. This was the Hellstorm, a tornado of seething magical energy. A pattern of enchanted fallout drifted across the southern United States and Mexico. The effects would not be felt immediately, but over the next generation, they would transform the world . . . Magic had come to the modern 20th century. But like the power of the atom on our own Earth, it would prove a Pandora's Box.
