Eventually, Leon stopped what he was doing and the last Obsidian Skeleton was born. In total, there were five thousand Obsidian Skeletons. Each of them started off with the initial strength of a Mid D rank. It was quite low compared to the starting points of Raegan and Darren, but Leon thought that it was nice and would give them more room to grow their own unique strengths over time. Plus, he had the resources back in the mortal realm to allow people grow quickly.
As a testament to that, Leon thought of the humans that he and Michael had brought back from Earth. His father, Eugene, had taken charge of the humans and together, he led them to grow through the Demon War. After the war, he had taken to exploring and clearing out dungeons on the Central Continent.
