Dr. Destinies Origins by MoonKnightFan101:
Nelson Strange was a successful, albeit egotistical and selfish, brain surgeon who enjoyed a life of wealth and luxury. Being one of the elitists, Strange was invited to Cairo, Egypt by an Egyptian ambasador. Being asked to help Egypt, Strange refused to donate in contribultion to poor Egyptian community. After going to the museum and discovering the art, Strange bought the Helm of Fate for $400,000 dollars. After leaving Egypt and going back to US, Strange was caught in car accident which disabled the nerves in his fingers. Despite spending half of his fortune on surgeries to fix his hands which never seemed to help, Strange almost quit just when he got a message for alternate treatment by an unkown source. The source instructed Strange thar there’s a healer in desert of Egypt but to meet him Strange will have to come with the Helm of Fate. Being desperate for treatment, Strange agreed and went to Egypt in his private jet. Searching for the healer under the desert heat for over 2 weeks, Strange almost quit again but he noticed a tent in the distance. He fell unconscious at the door of the tent and the tribesmen treated him until he woke up. After waking up, Strange asked are they the healers and the tribesmen answered yes, to which they answered his cure lies within the mystic arts. Strange was sceptical but they proved mysticism is very real and, over the next few months, Strange was being taught in their Egyptian magic. When the injuries were cured Strange was ready for the final course; to accept the duty of Dr. Destiny. Strange was instructed to put the helm on and immediately he was transformed into the most powerful sourcerer in the world, with access to hidden dimension within the Pyramid of the Sun.
