Mountain Glenn, Vale failed attempt at expansion. The project was abandoned when the Grimm, creatures of darkness, overran the huntsmen and huntresses that were assigned there to protect the workers.

Fearing that the Grimm would enter Vale through the tunnels that connected Mountain Glenn and Vale, the council ordered the tunnels to be collapsed. Trapping the remaining workers and huntsmen to their fate.

News of this tragedy spread to the other kingdoms, including the decision to collapse the tunnels. Survivors recounted their experiences, some even blame the council for refusing to send more huntsmen.

Lawsuits were filed, families and friends of the deceased were demanding answers on why such a tragedy was allowed to happen in the first place. Committees were formed to investigate the tragedy. The council was quick to reply to the public outcry, stating that they couldn't afford to send anymore huntsmen with the increased Grimm activity at the borders of the wall.

Survivors were interviewed by the committees. Even the huntsmen assigned at the borders were asked to confirm the council statement of increased Grimm activity.

Months of investigation, the committees was finally ready to publish their findings. They ruled that the council was in the right, collapsing the tunnels to prevent further tragedy was a necessary action. Even the decision to refuse to send more huntsmen due to the increased Grimm activity at the borders, was ruled to be a necessary action, due to the possible chance of a Grimm invasion of Vale. Though the council wasn't faulted for those two action, they were ruled as responsible for the tragedy by the committee.

...

When plans for the expansion were being drafted, the council decided to send only sixty huntsmen and huntresses to defend the three hundred workers. They were warned by the headmaster of Beacon, that such small numbers wouldn't be enough to defend the workers against Grimm attacks. The warnings were ignored and the plan was put into actions.

Day nineteen of the construction, the council received numerous reports from the huntsmen stationed at Mountain Glenn. The reports stated that they were stretched thin and they need more huntsmen to properly protect the workers. The council decided to send one more team of huntsmen.

Day sixty four of the construction, most of the infrastructure was nearing completion. Increased Grimm attacks was reported, though most of the Grimm were young, the huntsmen feared that the older Grimm may decide to attack as well. Reinforcements were requested, but the council denied the request to send more huntsmen.

Day seventy five of the construction, Minor and Major Ursa and Beowolves were spotted leading small packs of Grimm on the outskirt of Mountain Glenn. Reinforcements was requested again, and denied by the council again.

Day one hundred of the construction (two hours before the fall of Mountain Glenn), a small herd of Goliaths were discovered nearby and a flock of Nevermore were seen flying in the distance. Reinforcements were demanded or they will be forced to evacuate the workers. The council decided to recall huntsmen from the wall and from the badlands to assemble a platoon to assist the huntsmen assigned at Mountain Glenn. They would have been ready to deploy in a few hours at least that was the plan till they received the distress call from Mountain Glenn. The city was under siege of a Grimm invasion, and to make matters worse Grimm activity at the walls drastically increased. The council was faced with a dilemma either they send the platoon to help repel the Grimm invasion at Mountain Glenn or send them to the walls in case the Grimm decide to attack.

The lives of the many outweigh the lives of the few, as the council decided to send the platoon of huntsmen to the wall. They used this motto again when the Grimm breached the underground shelter, to collapse the tunnels.

...

Though the actions near the end could be justified, but what could never be forgiven is their negligence in the beginning. Ignoring the warning of the headmaster, and ignoring the huntsmen request for reinforcements multiple times. If they only listened to their huntsmen stationed at Mountain Glenn then this disaster could have been prevented, and because of their negligence they cost the lives of hundreds.

The council members were forced to resign from their positions, and face ten years of imprisonment for criminal negligence. The families of the deceased received compensation from the city of Vale for their tragic loss. New council members were elected and they quickly passed laws to prevent such negligence from happening again.

Though justice was served, the fall of Mountain Glenn will forever haunt the kingdom of Vale and it will be forever remember in history as another city that has fallen to the Grimm.

...

Forty years has passed since that fateful day, Mountain Glenn now serves as a nesting ground for the Grimm. The roads were overrun with weeds and other plant life. The tall skyscrapers were used as shelter for the avian species of the Grimm, at least the ones that were still standing. The smaller buildings were perfect dens for the Beowolves and Ursa.

In a few decades, nature will fully take back Mountain Glenn. In a century, nature will erase any trace that there ever was a city in the first place. Till then, this desolate metropolis will remain as a reminder of the threat Grimm posed to humanity.

The Grimm aren't the only ones to inhabit the desolate metropolis, deep in the underground mines of Mountain Glenn the White Fang decided to make it their base of operation.

The White Fang, once a peaceful organization that protested for equal rights for the Faunus, eventually decided that their old methods weren't working. If the humans won't give them equal rights then the Faunus would take it by force.

The leader of the once peaceful White Fang tried to dissuade them from path of violence, stating that it would only breed more hatred for the Faunus. But they refused to listen, they were tired of being a second class citizen. Tired of working in horrible conditions for less than minimal wage, tired of being deny services at businesses, and tired of the discrimination everywhere they go. They had enough and the peaceful protests accomplishes nothing.

Disheartened by the hatred in their eyes, the leader step down from his position and left the organization. And in his place four new people took his now vacant position. Each of them will be assigned a kingdom to operate in. The kingdom of Vale was assigned to a young bull Faunus named Adam Taurus. His was one of the best combatants in the organization and his cunning was unmatched.

Despite his youth Adam was highly respected in the organization. And he manage to lead many successful raids and attacks on known Faunus discriminators. His pupil Blake Belladonna, a female feline Faunus, was known throughout the organization as their best infiltrator and saboteur. She is able to blend in with her surrounding so well and move silently that even other Faunus can't hear her coming up behind them.

...

Their previous base of operation was an abandon warehouse in the industrial side of Vale. Though they were force to abandon it when a mole exposed their location to the Vale police department.

After executing the mole, Adam decided to move their base of operation to the wilderness, where they were least likely to be discovered by the police or the huntsmen and huntresses. Once the base was up and running, they once again began their raids and attacks.

...

"Sir, we received Intel from the Atlas division, that the Schnee will be transporting a large shipment of Dust to Vale" reported Adam's loyal Lieutenant. The chainsaw wielding Faunus has been with the White Fang since its formation, and his unquestioning loyalty to his leaders had him quickly rise up in the ranks. He like many in the White Fang had an undying hatred for the Schnee, with their treatment of the Faunus workers and their unfair wages. So when he received the Intel from the Atlas division about the shipment, he had to fight back a grin.

"Tell Blake to get ready." Replied the bull Faunus. Before the Lieutenant could respond to the order, a White Fang grunt burst through the tent flap.

"Sir, there a group of humans outside our camps. They are requesting an audience with you" the grunt relayed his message before the Lieutenant can reprimand him for entering the tent unannounced.

"The nerve of those humans, I will take care of them Sir."

"No, let them through. I want to know why they came here for."

"Yes, Sir"

...

It been months since that fateful meeting with the vile woman and her pawns. She requested an alliance, but he knew that the White Fang will be nothing more than her pawns to use as she saw fit. So he vehemently denied her request, and let her go. He will forever regret that decision, he should have killed her and her pawns there. But at the time he didn't believe her to be a threat. So when she came back the next day, something was different about her. The air became heavier and heavier the closer she got and her eyes glowed with malice.

She again made her request for an alliance and this time Adam knew it was a demand. And to confirm his suspicion she alight the ground in front of him. If there something Adam learned in his life is to know when he outmatch, and judging by the bodies of his men she can easily end him before he could so much as touch her.

He reluctantly agreed to the alliance. Before she left, she told him to move his base of operation to the Dust mines of Mountain Glenn.

It took him and his men weeks to clear out the Grimm in the mines and to set up the living quarters. Once the base was set up, he sent a squad of his men to map out the mines. He then sent another squad of his men to Vale, to help one of the vile woman's pawn with the Dust robberies. When he first met Roman Torchwick, he had to restrain himself from gutting the racist.

He will continue to obey her, but when she least expect it he will cut her down. Oh, how he will relish the surprise in her eyes as the light slowly fades. And once she is taken care of, her pawns will face a similar fate starting with Torchwick.

His musing was cut short when one of the men he sent to explore the mines came rushing towards him. He was carrying something in his hands, he couldn't tell what though as it was covered in a red cloth.

"Sir, we found something."

"What is it?"

"We found a sealed room, that look like it been sealed for centuries. And in the center of the room was an altar with a book on it."

"And you thought an old book was worth my time, why?"

"Sir, when we enter the room strange things starting happening. Our light started to flicker, we saw movement out of the corner of our eyes, and the closer we got to the book we started to hear whispers. Though that all stop when Mitch covered the book with his rag."

As the grunt was explaining his reasoning, Adam was planning on having his men checked by a Faunus who once was a psychiatrist before joining the White Fang.

Seeing the look of disbelief on his leader face, the grunt removed the rag. Suddenly all the lights in the room went out, and indistinguishable whispers were heard. Adam pulled Wilt from Blush, believing that he was being ambushed. But there was no one else except for him and the grunt. He could have sworn he saw movement out of the corner of his eyes. He felt a cold shiver run up his back and the whisper slowly became louder and louder till the voices were practically screaming. He was slowly being driven mad, then the voices went silence. A moment later the lights came back on. He looked over to the other person in the room and saw that he covered the book with the rag. With the disbelief gone from his superior eyes, the grunt asked what he should do with the book.

"I want you to gather any member who once were historian, professors, neurologist, or member of the scientific community. I want them to study this book, to find out what it is and why it causes these effects. But make sure to tell them, to study this book in short intervals, I don't want any of them to be driven mad."

"Yes, Sir" the grunt reply as he left Adam's quarter, taking the book with him. Maybe this book will provide him the solution to end the vile woman. It may also be the key that will finally place the Faunus in their rightful place as rulers of this world, and humanity will finally know what it like to be treated as a second class citizen. Only time will tell.
