The Goddess Athena, the Devil, and their daughter both had to take action in this regard because they knew everything about them; so, they decided to hide for a while, until they forgot what they had done.
While they were in hiding, they began to devise a plan of revenge, against the children of light, the children of darkness, and their respective parents.
"The first thing we have to do is separate them and let them hate each other," said the Devil.
"And after that, what else do I have to do?" Athena asked.
"After you have achieved that part, what you have to do is, sow the doubt of mistrust between them, so that they begin to doubt each other and for everything," said the Goddess Athena.
And what else do I have to do? Tell me, please, the whole plan so that I can carry it out, "said Athena.
"Ok, the plan is as follows: First, you have to earn the trust and friendship of their adoptive relatives, their friends, and their acquaintances and once you have achieved it, start small and cautiously, to turn them against the children of darkness and light, "said the Devil.
When that time passed, Athena decided that it was time to take revenge on each one of them, for the humiliations that her mother and she had undergone; so, he decided to take on another physical appearance, to start executing his revenge.
Athena knew she had to change her name if she wanted revenge on each of them, for the humiliations that both her mother and she went through, and it was then that she decided to call herself Annabeth Chase, to mislead, and to humble them.
The second thing he had to do is, learn to live among humans and learn everything about them; especially about the adoptive relatives of the children of darkness and light, and he had to earn the trust of his friends.
When he managed to conquer them, at the point of deceit and interacting with them for two months, he decided that it was time to turn them against the children of darkness and light.
But he had to tell his parents about his plan for revenge. They were happy with the decision of their daughter, Athena, and gave her the green light to start turning them against the children of darkness and light.
"Remember, daughter, that they have to be confronted and that their hatred prevents them from working together, in the war they will have against us," said the Devil, while hugging his daughter.
"And you have to do the same with their parents. Remember that they cannot suspect us; far from it, of our plan of revenge ", said the Goddess Athena, as she joined the embrace of parents and daughter.
"Don't worry, parents, you will never know about our plan, or about our hidden intentions," replied their daughter, Athena, full of hatred for them.
"Daughter, remember that you have to make everyone see the worst of them or at least the worst of the children of darkness and that they fear being near them and finally, that they curse having known them", said the Devil, starting to mount revenge against them.
"Remember also that, you have to do the impossible so that they do not reconcile, and if they manage to reconcile, that doubt remains between them, which is the doubt of betrayal", said the Goddess Athena.
"Don't worry daddies, because I will do exactly what you have told me so far, and I will not disappoint you. I will do everything in my power, to separate you and forever," Athena said, sure of herself.
"We know that just be careful what you are going to do, and as soon as you have managed to complete the revenge plan, get away from them, before it is too late. Remember the following: more or less I will calculate the time in which you finish your revenge, and I will start mine and be merciless with humanity, especially with the children of light, because their parents were the ones who hurt me the most, "said the Devil.
"And I will take revenge on the children of darkness, because they, like their parents, hurt me and humiliated me too much, and now, it is my turn to take revenge on each one of them," said Goddess Athena.
