The New Light of Hope: Books I to VI.

Chapter IX: Amanda Angel and Maria Memory.

Just like the humans, the animals of the forest also have overseers and spirits that they follow and ones that will never betray them, but there are also those that will try and destroy them; they are known as the Four Sisters; Diane Devil, Amanda Angel, Maria Memory, and Gabriella Glitch.
Diane is the oldest of the four; she is the ruler of the Evil Spirits Division and is the main leader overall; animals who sin against the Code of Conduct or people will be sent to live with her for all eternity.
Amanda is the second oldest of the four; she is the ruler of the Spirit Runners Division and is the main leader overall; animals who follow the Code of Conduct or people who do not sin will be sent to live with her for all eternity.
Maria is the youngest of the four; she is the ruler of the Vision Realm and is the overseer of all the mortals that live on Earth, she determines whether animals or people who have passed on are suitable enough to live with either Diane or Amanda depending on what they did during their time on Earth.
Gabriella is the second youngest of the four; she is the ruler the Corruption Realm, those who are dragged into her realm will come out corrupted. With each Generation, the Heroes are strictly required to meet the sisters, whether they were told to do so or not. And that is where the next part of our story begins.

Aurora:

The following night after we had visited the Night Runners Division, had returned back home to our families. After I ate, I went to bed and drifted off to sleep—however though, we were instructed not to visit the forest for two days by GorseHunter, he did not give us any specific reason however, only that we must stay at our homes and return after the two days have passed. But we would later learn that there was a reason as to why he told us to stay at our homes.
…
That night, I dreamt that I was in some sort of dark abyss in which looked like that there was nothing more than endless darkness with no way out. But I soon found my friends, though they were just as confused as I was wondering if all of this was real or not. "I can't tell if we're actually having the same dream or not, or if I'm just going crazy." Summer said.
"You are not going crazy, Summer. All of you are here at the same time." A voice said. At that moment, Summer sprung into action—she ordered us to stay behind her and then yelled out: "I don't know who you are or what you want or how you even know my name, but whatever you're up to or whatever you want from any of us, you better back off now!" At first, there was no answer, but soon enough, two figures made themselves known to us. One was a female pig spirit with white skin, hair and wings, light blue and yellow clothing, and blue eyes with yellow pupils, she also gave off a small luminaries glow as well; the other one was also a female pig spirit, but with pale white skin and black hair, dark gray and black clothes, and black eyes with white circles around her pupils. "In fact, we are in no way minatory, nor mauvais." The black haired figure said. We all got from behind Summer, but we were still aware of what was happening. "What... Who exactly are you two?" Summer asked. "Well, I am Amanda, Amanda Adler Angel." She said. "And I am Maria, Maria Madden Memory. We are known to be one of the Four Sisters."

Summer: "The 'Four Sisters'? And just what exactly or who exactly are they?"

Maria: "Well, the oldest of the four is my older sister, Diane. She rules over the Mauvais Spirits Division, or what the mortals call 'hell' or 'the underworld'."

Amanda: "I am the second oldest and I am the ruler of the Spirit Runners Division, or the afterlife. The members sometimes refer to me as 'Chief Amanda' on a count that I am the chosen leader. That is where the 'Chief' for the leaders of the Forest had originated from. The name is also shared by the leader of the Heroes as well."

Sadie: "Well, that part makes sense."

Maria: "I am the youngest of the four and I am the ruler of the Vision Realm and I am the overseer of all living mortals. When animals or people pass on, they will appear in this Realm and what I see is what determines whether or not they are suitable enough to live in the Mauvais Spirits Division or the Spirit Runners."

Amanda: "And as for the youngest sister, Gabriella, she rules over the Corruption Realm, those who are dragged into the Realm will come back out corrupted. We are on your side while Diane and Gabriella are on the opposite side."

While it all made sense, I was still very confused as to why they were here telling us all of this and so I asked: "What exactly does any of this have anything to do with us?"
At that moment they got serious. "Eight young civilians, one destiny." Maria said. "What's that supposed mean?" Summer asked her. "You are all going down a path that is in the same direction with one goal afoot. This 'Heroes of the Forest' business is no joke; it is real and is something that should be taken seriously rather than being joked about as if it is not that big of a deal. With this also comes with new responsibilities and tasks that when given by a leader, co-leader, Healer, General, Captain, Lead Hunter, Lead Tracker, Lead Messenger, or any of the animals, should be completed almost immediately once given. You are to also sort out conflicts or scuffles that break out between the animals if they were to do so and come up with a sort of solution. Many of you may not truly know what to do at first, but once you understand what to do, you will begin to get used to it soon enough." Amanda told us. "Understood?"

Bellatrix: "Yes, ma'am."

Amanda: "Good. But before we leave, there is another warning that we must give you."

Milly: "What is it?"

Maria: "A terrible yet dangerous, heartless threats lurk within the forest with a desire to kill and thirst for blood, combined from all of the past threats merged into one with one of the leaders rising back up seeking vengeance and power to take over the whole Forest because of the megalomaniac that he is. But with the power of eight who will later become sixteen and with the help of the Forest, they, along with the animals of the Forest, we be able to defeat, even if it costs the lives of many animals young and old."

Aurora: "What?"

Amanda: "Do not worry, you all will understand soon enough."

Maria: "Until we meet again, Heroes."

They then vanished.

I later woke up soon after, then I laid right back down—but Maria's words came to me soon after.
A terrible yet dangerous, heartless threats lurk within the forest with a desire to kill and thirst for blood, combined from all of the past threats merged into one with one of the leaders rising back up seeking vengeance and power to take over the whole Forest because of the megalomaniac that he is. But with the power of eight who will later become sixteen and with the help of the Forest, they, along with the animals of the Forest, we be able to defeat, even if it costs the lives of many animals young and old.
What did it all mean? Was it some sort of prophecy or omen we were supposed to be aware of? But most importantly: Who was this "threat" they were talking about?

Well, friend, we would later learn what it all meant soon enough.
