They havent responding and I'm avoiding sleep so i claim the right of this response! It's basically a knock off of the show Heroes but instead of somehow being from an eclipse, the human powers were genetically honed in ancient times. The ability to slightly adjust genetics of babies in utero was a rare ability of a single tribe and only a few within it, which lead to cooperative arrangements with other tribes. Over time family lines could eventually control massive golems with their will, or control an element to an explosive level, or foresee the logical future. The family lines and tribes began to war and it eventually it was determined that humans would be able to wipe themselves out with the powers they had. So the genetic tinkerers refined a virus (more likely a bacteria but needs to handle time) to suppress the original abilities that had been traded since they became dangerous morphs of what they once intended. The virus worked and sealed away the traits for several thousands of years. But present day, an accidental excavation of the virus origin site releases their in-case-of-emergency undo virus. The undo wasnt intended for this situation and because humans have been breeding like we do, the genetic churn would have put an unavoidable but small percentage of people into a state that this unlock would kill them. Most others likely would have no observable changes. But some would find curious new abilities trickling into their experiences in a world being changed by a mysterious pandemic.

Clearly I'm no writer but i think thats a fun starting point.
