Absorb.

Looking around you see Amari, floating ****. You grab her and pull her closer. Her skin is soft and oddly human. You hug her from behind and can't not notice it when her ass touches your dicks, but this will have to wait.

After you have her in your arms, you Absorb with all your power. You feel her power being absorbed, but with her power her skills, with her skills her stats, and with her stats her memories.

One of these memories is one of Amari talking to her sisters. You can't hear what she's saying, but it's not a problem because you remember it. She's begging her sisters for some power so she can defeat the Men that are invading her land, but they won't lend it. Amari proposes a loan with interest, and they accept it. Using the power lent and part of her own, Amari creates a certain pond in a certain valley. Half of the pond being made of her own power and the other half divided by her three sisters.

After Amari's Pond is corrupted by corrupt women, Amari is unable to take it back, so she is unable to return the power she took from the other goddesses. They are very angry and curse and humiliate Amari, who leaves. Many years pass and the goddess decides to create a **** to protect the pond so no one will steal that power, since most of it belongs to her.

Amari's influence on the world grows. Even though she dedicated most of her power to the pond, she's the only goddess capable of growing more powerful so she eventually reaches her full form again, while the others are handicapped. They try individually sending a few people to recover the access to the pond, but Amari doesn't allow it, and she's more powerful than each one of the three.

That's the point you begin to understand everything. After so many years trying to steal the powers in the pond by themselves, the three goddesses join forces. One of them, responsible for creating and killing the monsters, creates a certain Weed Fiend with a real mind. The other allows it to grow and level up endlessly, becoming smarter and more powerful. The third gives it a purpose, and a will: it WANTS to invade the fortress and find the pond of Amari.

None of them give it limits though. Amari talks to the other sisters about what they did, the creature has started a chain of events that can not be stopped, for it is too powerful to be stopped. They don't take her seriously.
