In the middle of the 20th century, a radical molecular biologist called Professor Ligroi thought he had discovered the formula for immortality. But, he still needed two things, the money to run the immortality trials and willing people to run the trials on. A shadowy society of the super-rich caught wind of his breakthrough and gave him what he needed; all his funding and 10,000 test subjects.
He moved his equipment to Egypt, where he built a vast underground laboratory deep in an ancient mine. On the 12th of September 1951, he gathered together all his test subjects. In small doses, his formula may have even worked, but we will never know. As soon as the trial was ready to begin, the huge vat containing the immortality formula cracked, spilling the liquid all over the floor and filling the old mine. Instead of making the people, it came into contact with immortal, it went one step further, it made them supernatural. The formula disintegrated their physical forms until they were vapor-like figures, figures of smoke. Until they were genies.
