No no, the daimons were a genetically altered soldier species equipped with magneto-plasma technology that allowed them to initiate combustion anywhere there was sufficient oxygen. The three members of the Light were holographic representatives of a sentient supernetwork like a greatly advanced form of the Internet, that could alter particle alignment and focus cosmic radiation to varying degrees onto the surface.

The same sentient supernetwork entity created the nanobots to reanimate dead tissue, performed experiments on the monsters to control them, created daimons and gave them their weapons, and projected the three avatars. All this was one huge Xanatos Casino Resort City garnered towards testing whether living humans would be worthy as the next species to undergo "transcendence".
