As the Devil, I had made many deals in my time. Some were for power, some for wealth, and some for personal gain. But the deal I made with the man who sold his children was one of the most unusual I had ever struck.

At first, I thought it was a simple bargain - he would give me the children he sired in exchange for a favor each time. But I quickly realized that this man was not like others. He was a sperm donor, and his ability to father children was beyond what I had anticipated.

As the years passed and the number of children he sold to me grew, I began to feel the weight of my own foolishness. I had not thought through the consequences of this deal, and now I was facing a situation that was spiraling out of control.

The children were everywhere, and they were starting to cause problems. They were demanding favors of their own, and their mothers were starting to ask questions. I can't stand mothers. Always nagging about their children. I knew I had to find a way to put an end to this madness before it was too late.

In the end, I decided to cut my losses and end the deal. At first, I tried to end the deal without asking for anything in return. I summoned the man to my domain and explained to him that I could no longer continue with our arrangement. He was disappointed, but he understood. He understood too well. The man was clever, and he saw an opportunity.

He asked for something in return, something of great value. He wanted the power to control the minds of others, and the ability to bend them to his will. Just imagining the echoes of those countless mothers, I had no choice. And knowing that I could not refuse, I agreed to his demands. The price was high, but I had no choice. I knew that if I didn't give the man what he wanted, he would make life even more difficult for me. This man's fertility knew no bounds. So I granted him his wish, and the deal was done.

But the man had not anticipated the full extent of his powers. He soon discovered that he could even control the minds of powerful beings, such as the Devil himself. And with this newfound ability, he turned against me.

I was caught off guard and powerless against his will. The man used his powers to bend me to his own desires, and I was forced to do his bidding. It was a humbling experience, and one that I would not soon forget. It started off small -- he used me to curse entire bloodlines, to amass riches, to enslave towns. But this usage grew more with every passing day.

Eventually, the entire world was bending to his whims. Immortality and invulnerability were early on his list of desires, so he feared no one in this realm. All of Earth began serving his every desire; and his desires were always selfish. With every yacht he had, he wanted a bigger one. He began building spaceships of immense sizes, using unimaginable quantities of fuel like a volcano eruption every minute. The greenhouse effect took the surface of the Earth into a scorching hellscape.

Logistics supply chains crumbled apart and all the skies glowed a violent hue of red. Volcanoes erupted from the increased pressure and temperature, covering much of the surface in molten fire and ash. The people screamed and their teeth gnashed.

He built a fortress, and all the people wanted to serve him to receive the luxuries of his way of life. He had lords serving him, and those lords had followers as well. He made promises and deals with them to further entrench their loyalty, beyond that of simple mind control. He discovered interdimensional travel from me, which allowed him to subtley influence other realms, just as I did to his. Eventually, he started making deals with them, wanting to gain other dimensions for himself.

By the time the "man" became aware of what was happening, he was much too far gone. My realm had already consumed the Earth, and my influence consumed him. I am the Devil, after all; my being spans across universes, and though I may appear physical, it is a mere projection; I am simply a force of reality beyond the confines of words or deals.

I am the primordial force of greed. Those who possess me, become me.
