This issue was a big one. It meant that there would never be a natural ecosystem, not in the truest sense. If Darius wanted wildlife to exist, he had to create it somehow.
This was an issue of such difficulty that he couldn't even describe it to you. Darius may have access to the Spirit element, but one could not create souls out of nothing.
Perhaps the Element Discoverer might have created a Grandmaster or Divine grade spell of such a nature, but it was impossible for others. The best one could hope for was to manipulate or control already existing souls, which was the traditional use of the Spirit element.
Like with the Material element, Darius wasn't able to create an item or material from nothing. He could only change one from one state to another. That was just how the various elements worked.
