Unknown to even Phosim, another entity had been forming over all this time. Phosim being all light had to be balanced with another of all darkness. And so Mal came into existence. Mal was greeted and welcomed by Phosim who was unaware of Mal's inner soul. He was twisted and tainted and wanted only to destroy all that Phosim had created. However sly as he was he hid his dark side and bided his time until he could bring down all Phosim had made.
Necrona and Aeronin
Phosim noticed that some of his creations were cruel to others and would commit heinous crimes such as murder and adultery. So he created 2 dimensions parallel to theirs and made them each opposite. One was a beautiful land in the sky, the Aether, ruled by Aeronin. The other was a hideous twisted world under the bedrock, the Nether, ruled by Necrona. Good souls when they died went to the Aether and were rewarded for their lives. The cruel souls went to the Nether and would forever be tortured for their crimes.
Hydranon, Terranus, Pyrojin and Skyla
The forces of nature on Phosim's world were uncontrolled and destructive to his people. So he took the essence of the different elements; white hot magma, the purest pearls from the bottom of the ocean, a cloud from the highest point in the world, and a chunk of earth remote to any of his people. From the essences he formed four beings and he sent them to earth to contain and command their elements. They live upon earth but cannot be seen by normal mortals.
