A former king of the Inhumans as well as the founder of the Terrigen Mists. Randac ruled Attilan thousands of years ago. Randac was keenly interested in the mysterious properties Terrigen. Terrigen was a crystalline mineral that had been discovered in subterranean alcoves beneath the city. Randac felt convinced that these crystals were a key to his peoples’ destiny and he conducted numerous experiments upon them.
Randac rendered a collection of the crystals into a gaseous form and decided that he must expose himself to the result mist. His advisers pleaded with him not to take this risk but Randak would not be swayed. He entered into the specialized chamber where his body was bathed in the Terrigen Mist.
Somehow, Randac’s activities on Attilan caused a Kree Sentry to activate in nearby Iceland. The Kree scientist who had originally experimented on The Inhumans had left the Sentry behind to monitor what would ultimately become of the Kree’s abandoned experiments. Sensing Randac’s activities, The Sentry activated and quickly made its way to Attilan.
When Randac finally emerged from the chamber of Terrigenesis, he discovered that he had been imbued with super powers, enhanced strength and the ability to emit powerful force blasts from his hands. The Sentry was there waiting for him. It decided that it was impressed with Randac’s discovery and stated that Randac had ascertained the true purpose of The Inhumans. For this reason, the Sentry declared that it would not destroy Attilan and would instead leave the Inhumans in peace.
Over time, many Inhumans subsequently followed Randac’s example and subjected themselves to the Terrigen Mists. As the years went by, Terrigenesis became a ritual that most all Inhumans would undergo during the time of their adolescence.
Whereas Randac received impressive powers and his physical appearance was left unaltered, this was not always the case for other inhumans. Some were bestowed with relatively meager powers and others were physically mutated in dramatic fashions. It was believed that haphazard nature of Terrigenic transformation was actually the result of an individual’s genetic makeup and inherited qualities of one’s family lineage. A Genetic Council was formed to attempt to guide the process of Terrigenesis, to utilize the process of prearranged mating practices in an effort to ensure preferable and advantageous results from the transformation of Terrigenesis.
Randac lived out his kingship and went on to be viewed as the founding father of Inhuman culture on Attilan.
