* MONSTERS & HUMANS.

1 - Bedtime Story

since the beginning of time, two races ruled over the world, HUMANS and MONSTERS.

they lived in harmony and joy.

until, one stormy night, a merciless war started between the two.

the MONSTERS were too weak and unprepared for a war, and their race fell apart.

the HUMANS ended up victorious, and decided to hide the MONSTERS from humanity in the underground with a magic spell.

many years later...

1. One Rainy Day

LONG AGO, THE EARTH WAS DOMINATED BY TWO SPECIES
HUMANS, AND MONSTERS
THE TWO LIVED IN HARMONY
UNTIL ONE DAY...

A RIFT BETWEEN THE TWO SPECIES
CAUSED CONFLICT TO BREAK OUT
AFTER THE DUST SETTLED, THE MONSTERS WERE SEALED AWAY
THEY HAD TO FEND FOR THEMSELVES

PRESENT DAY
YIMMETT GULF

HUMANS have grown weary.
Love and war.

001 - Forgotten Memories

* In the days of old...
* Two races existed upon the earth.
* HUMANS.
* And MONSTERS.
* They lived peacefully together for some time.
* Until, tensions arose, and a war was soon waged.
* Monsterkind fought valiently... but was defeated in the end.
* They were sealed under the earth by powerful mages...
* Never to be seen again.

* However...
* There is still hope!
* There will come a HERO, heart fueled with resolve!
* Weapon in hand, they will strive to finish what was started!
* The shining hope of the underground, they will strike against those who have wronged them!
* No matter the cost, they will refuse to back down or run away...
* The HERO will strive on towards their goal until it is completed!
* Monsterkind shall be set free!
* Have hope, friends, for the HERO shall set us free!

Folklore

ONCE UPON A TIME, THERE WERE TWO RACES...
HUMANS, AND MONSTERS!
THEY GOT ALONG AT FIRST, BUT ENDED UP FIGHTING.
EVENTUALLY, IT BROKE OUT INTO A WAR!
AFTER BATTLING, THE HUMANS THOUGHT IT WOULD BE BEST...
TO SEAL THE MONSTERS UNDERGROUND.
ON THE SURFACE, HUMANS ARE ADVISED NOT TO CLIMB THIS MOUNTAIN...
WHERE THE LOST CIVILIZATION OF MONSTERS RESIDES.

001 - Awesome Story

Not much to say for this one. It was fun experimenting with the composition.

001 - Once Upon A Time

"A long time ago, two races dominated the world:
HUMANS and MONSTERS."
"Then one day, a war has been declared between the two races."
"After a long battle, turns out the humans were victorious."
"They sealed the monsters away with a magic spell."
"A magic spell that makes monsters trapped inside the underground, for a long time."
"Many years, later..."
"MT. SERECH, 200X."
"Rumors said that those who ever climbed the mountain,"
"... Will never come back."

001. A Beginning

* Long ago, two races lived upon the earth:
* HUMANS and MONSTERS.
* Each race lived amongst the other in peace and harmony.
* And yet, peace was not meant to be.
* Tensions rose, and escalated into all-out war.
* Monsters fought valiantly agains the humans.
* But, in the end, the humans were simply far too strong.
* Humankind was the victor, and, as punishment, monsterkind was sealed underground.
* Using their strongest magic, a barrier was formed, trapping the monsters underneath for all eternity...

MT. EBOTT
201X

* The monsters still lie trapped underground to this day.
* Salvation seems impossible.
* However, once in a blue moon...
* A new star is born.
* Perhaps they can be the salvation monsterkind so desperately needs...

* Many humans have ventured down the mountain to finish what their ancestors started long ago.

1. Once Upon A Time (Spun)

Bob Lion - UNDERSWAP Soundtrack - 01 Long Ago

Long time ago, monsters inhabited underground for generations.
Despite the backward development, life was fulfilling.
One day, humans visited the land. The blending of two civilizations ushered in a new era of prosperity for the world.
Later, the bond of humans and monsters cracked. A war broke out between the two races.
Humans emerged victorious by an overwhelming advantage.
They exerted magic, which monsters used to be proud of, to seal the remnants of monsters back underground, and imposed a curse to them.
MT. DISSAFOLS

Though it had not been so long yet, few people were aware of the living beings buried beneath the mountain.
And those who broke into that place, were never to return.

1. Pathetic Story

LONG
LONG AGO

IN A WORLD
FAR AWAY

TWO RACES ROAMED
THE EARTHS LAND ASTRAY

HUMANS
MONSTERS
A NEW JOURNEY TO EMBARK

BUT LITTLE DID THEY KNOW
THIS WAS ONLY THE START

A WAR WAS DECLARED
TENSION FILLED THE AIR

AND WHEN ALL WAS SAID AND DONE
THE HUMANS HAD PREVAILED

USING THEIR GREATEST WIZARDS
MONSTERKIND WAS SENT AWAY

NEVER AGAIN TO WITNESS
THE BEAUTIFUL LIGHT OF DAY

MANY YEARS PASS 
A NEW HUMAN PRESENTS THE LAST

JUST ONE MORE SOUL
TO TAKE BACK CONTROL

LEGENDS WERE SAID
THAT THOSE WHO WERE LEAD

WHEN THEY ENTER THE MOUNTAIN
THAT DAY MARKS THEIR END

In A Land Far Away

"In the past, there was a legend"
"A legend, of HUMANITY and MONSTERKIND"
"MONSTERS, HUMANS, they developed a series of fierceful battles"
"The HUMANS, were victorious"
