The Origin Land was vast. To an Old One, this place is infinite; even Rowan had not seen the end of this mysterious dimension because it was ceaselessly expanding.
Rowan could not even begin to harness the true power of this place, despite the power coming from him, because it was new, and everything he had been doing with it for so long was replicating the methods of his dimensional powers, but he knew that this was not the best method of utilizing this power.
In one corner of the Origin Land, Rowan had rebuilt the city of Sheol, a city that was so massive it could as well stand toe to toe with an eternal realm in size and complexity.
This city was to be the home of his children, and in time, he hoped it would become the bastion of life for all of existence. For something like this to happen, it helps that this city could continue to grow with every new life form that it collects. Sheol was alive.
