There Hills were her shrine. They had been created for her. She had created them for herself, along with the rest of the world.
When the succubi were first introduced to the universe, they quickly realized that they would not be able to survive in groups. Their constant need for desire and worship would lead not only to fighting and jealousy, but to the rapid depopulation of the world. Each set out to create her own world, with her own feeding supply, and she had created this one.
She made it beautiful, with deep seas, wide plains, flowers of every color, and rolling hills. The hills were her favorite part.
Then, she populated it with worshippers. Her worshippers, of varying degrees. She planted people like seeds, sowed reverence into their hearts, and watched them grow. As they grew, she walked among them, cultivating societies and expanding civilizations. It took her 1000 years.
At first, she fasted, not wanting to feed until the world matured. Then she realized her hunger was blocking her progress. When she grew weak, her world faded. People bickered, and the hills began to die. So in order to protect her work, she broke her fast.
It was easy. The whole world loved her. People travelled to bring gifts to her Hills. Every day, a new person offered Themselves to her. Some she immediately took into her body and devoured. With others, she went into their minds. All she had to do was Look at their eyes, and she got into their souls. They would become enchanted, mindless, and run across the world doing her bidding. With other bodies looking after things, she was free to retreat into the Hills. Eventually, her hold on the souls would wear on her ambassadors, and they would return, obsessed with the idea of connecting with her fully. They would beg to be devoured as well, and she would oblige. It was all out of love. She loved them.
That was why she left, finally. It occurred to her that it might have been wrong to create life simply to be used and destroyed. She wasn’t sure how morality worked in a world of one’s own devising. Still, some part of her felt monstrous, especially when she watched the surviving family members of her sacrifices. She could see their loss, and it made her feel lonely. Everyone loved and worshipped her as strongly as ever, but that too began to feel bad.
She knew that if she were to stop feeding, the whole world would die. She also knew that she no longer wanted to feed on her own people.
So, she made arrangements. She shielded her eyes and took lovers without eating them, willing herself into pregnancy, and maturing her daughters into priestesses. She only had daughters, and they lived in the hills. Her daughters had her blood, her mind, and her eyes, but they had their fathers’ hearts. Thus they could enchant and bewitch and entice, and as they coupled with worshippers of their own, the world continued to flourish. But they could not feed as she did, which made them almost perfectly safe.
Then, she left. The rest of her life was spent casting around the universe. Fifty years were spent ruling a nation in the Eastern Earth. Daughters and prosperity remained wherever she had been. At what should have been the end of her life, she realized she had left enough energy behind her to stick around intangibly.
She brought her body back to her Hills, finding them as glorious as ever. Most of her priestess daughters had set out on their own adventures, but a few descendants remained. When her body died, her spirit sank into the hills. Every so often it would lust itself out of the hills and find amusement by jumping into a descendant at random. In this way, her exploits continued, and her world prospered even more.
