Undercurrents...

Unknown Time Earlier, Outside of the Azeroth

The world of Azeroth was a beautiful world that was comprised of four major continents, with a number of islands scattered about them. The Great Sea was located in between the four landmasses, and at the center of it is the Maelstrom: a massive chaotic whirlpool and all that remains of the ancient Well of Eternity.

To the east lies the Eastern Kingdoms, which is made up of three major regions. Azeroth to the south, Khaz Modan in the middle, and Lordaeron to the north, these last two separated by a channel and connected by the dwarven bridge of Thandol Span. To the west, across the ocean, is Kalimdor, which is also divided into three regions.

North of the sea lies the frozen continent of Northrend, and to the south, the newly discovered landmass of Pandaria, which had been isolated and shrouded by dense mists during the last 10,000 years. The islands of Zandalar, Kul Tiras, and the Broken Isles have been of major importance in recent events.

No matter who was observing the sky, everyone from the lofty Grand Magister of the Quel'Thalas, Druids of the Cenarius Circle on the Kalimdor, Archmages of the Dalaran, Monks of the Pandaria or anyone who looked at the starry sky noticed the phenomenon of the stars.

A flaming Twin Tailed Comet was falling down on the world of Azeroth, with all of its beauty and mysticism, and everyone who looked at the falling comet could feel that something was changing with its arrival.

The heralding of the greater and tumultuous events was coming together with the Twin-Tailed Comet as it disappeared into the depths of the Eastern Kingdoms. 

Not only did the so-called mortal races notice it, but also the dragons of the Azeroth of various Dragonflights noticed the presence of the Twin Tailed Comet, and they could feel far more from the arrival of the Twin Tailed Comet.

The first ones to notice these were the dragons of the Bronze Dragonflight as the eternal guardians of the time; it was them, who were most affected by the Twin Tailed Comet.

Caverns of Time: The Past, The Present, The Future

The Bronze Dragons were the dragons whom the Titan Aman'Thul blessed and tasked with the protection of the Time itself when he blessed the Nozdormu and his bord with the ability to time travel and mastery of temporal Magic. Generally stoic and detached from 'current' events, they are rare to interact with mortals unless they require help in safeguarding the one true timeline.

Their sole purpose was to protect the time and not intervene in anything else, not even the matters of the other Dragonflights or whatever. Such was their purpose and task given by Titan Aman'Thul himself.

Just as every single day, Chronormu as responsible Temporal Investigator, was observing the timestream of Azeroth. Compared to the other Bronze Dragons, or even all Dragons that preferred to take the forms of the High Elves or Night Elves, she took the form of Gnome, whom she thought were adorable little creatures. 

Thus came into existence her nickname... Chromie.

Just like every single dragon in the existence, she too felt the presence of the Twin Tailed Comet that orbited around Azeroth for a time, before it crashed somewhere in the depths of the Azeroth Continent.

"Just what is..."

Before she could finish the sentence, suddenly, the streams of time started collapsing one after another as time changed. This was perhaps the worst news for the Bronze Dragonflight, as Chronormu started searching for the change in the timeline that caused the tremors in the streams of time.

"Fall of Stormwind... It's gone. Not only that, but what is the Covenant? And the New Horde is significantly weaker and smaller, almost negligible compared to what was destined... everything is collapsing..."

Chronormu said with dread in her childish voice, completely not befitting the persona she was appearing to be. Suddenly, the time streams were changing at lightning speed; many things that were supposed to happen didn't happen at all.

Some happened entirely differently compared to their fated end, and some entirely new events appeared in the streams of time, as everything that the Bronze Dragonflight had cultivated and created for many millennia was falling apart like the house of cards.

"Sa'at! We need to scour the timeline after the opening of the Dark Portal."

She screamed at the Bronze Dragon with the appearance of a High Elven noble wearing golden armor. Sa'at was one of the strongest combatants of the Bronze Dragonflight and was one of the Bronze Dragons who was managing the section of the oversight together with Chronormu.

"On it."

Suddenly, the Hero of the Bronze Dragonflight started casting some of the Spells and checking the temporal occurrences and the reason why the timelines started collapsing, something that was threatening the very own existence of the Bronze Dragonflight.

Soon enough, he had his answer as the dreaded realization came to him. In a split of a second, he was ejected from the streams of the time and coughed a huge amount of blood as he attempted to look into the streams of time.

"Sa'at!!"

Chronormu immediately rushed to her fellow Bronze Dragon and cast several healing spells on the Sa'at, who seemed to be severely injured. Even though she wasn't most apt at the healing Magic, she was still dragons and dragons were best at Magic. 

It was like second nature for them, especially the Blue Dragons of the Blue Dragonflight that were incarnations of the Arcane Magic itself.

"I saw it... a man with warhammer and disposition of higher mysteries related to the Twin Tailed Comet... he is the nexus of all changes that are happening."

The Temporal Investigator looked aghast because it seemed that they would need to intervene and destroy the anomaly before the situation got even worse, but before anything could be done, suddenly, overwhelming power descended upon the entire Caverns of Time.

Immense power descended out of nowhere on the entire Caverns of Time, which started shaking, and large parts of them were collapsing, crushing some of the unlucky Bronze Dragons who were crushing in the falling debris.

"No one touches the Chosen Lord!"

A strong and powerful shrieking female voice echoed through the entire Caverns of Time, as all Bronze Dragons were imprisoned in the Caverns of Time for an indefinite time when a crystalline barrier appeared around the Caverns of Time.

'It's like the presence of the T...'

Thought rushed through Chronormu's mind as she, too, was knocked out by the sheer power that descended down on the Caverns of Time. The last thought that was going through her mind before she was knocked out was that the Caverns of Time were going to get sealed for an indefinite time until it was too late for the Bronze Dragonflight.

In the meantime, the entire Caverns of Time, were beating sleaed from the rest of the Azeroth by the invisible power.

Though it was not only applied to the Caverns of Time, but the other places where the Bronze Dragonflight was known to have their strongholds and places were also sealed from the rest of the world.

Around the same time, undisclosed location.

Somewhere surrounded by huge trees and green grass, a woman wearing garbs of sorcerer of white color with long blonde hair was meditating. Suddenly, she opened her eyes as she looked high in the sky and observed the falling Twin Tailed Comet.

"The first that outburst of the Fel and now this... it seems that I would need to go to the south and scout the area..."

Several weeks prior, she felt a tremendous outburst of the Fel, something that almost every creature attuned to Magic on Azeroth felt ripples as the something in the southern Azeroth flared to life.

She knew what it was, and it greatly pained her just to think about such a thing. It was right now clear that she would need to depart there to see it with her own eyes; previously, she, too, planned to visit the Stormwind to see her son, if he was really in cahoots with the Burning Legion.

Now, she needed to change the target, as the place where the Twin Tailed Comet fell took precedence because it was something on the same level as the opening of the Dark Portal that she sensed some time prior.

After she finished the meditation, she stood up and slowly headed somewhere to prepare for her journey to the south. Turmulous time were coming to the world of Azeroth, and they would need to be strong for the hard times that were awaiting them.

Especially when the suspicions that she had were true...

Because then it would have apocalyptic proportions.

Northwest of the Northern Kalimdor

In the west to the Eastern kingdoms, beyond the other side of the Great Sea, the mythical continent of Kalimdor where the Nigh Elves were still remaining after the Great Sundering, though in a vastly different society that the ancient Kaldorei Empire that once in the distant past dominated the entire super-continent of Azeroth.

The ancient Nigh Elf civilization spanned most of the old Kalimdor and dominated the world. It was the golden age for the Nigh Elves and especially the Highborne that ruled the Kaldorei Empire.

The empire thrived and prospered for thousands of years, until the beginning of the War of the Ancient, which was started by Queen Azshara and her faction of Highborne that attempted to summon the Demon Lord Sargeras into the world and soon enough..

Everything broke up.

Tyrande Whisperwind, the chosen High Priestess of the Goddess of the Moon Elune, the former general of the Nigh Elf Sentinetns and current Head of the Sisterhood of Elune, was praying in the depths of the main temple of the Moon Goddess within the Darnassus.

She was known for being an elf of extraordinary beauty. Like many night elves, her skin is purple, she has long aqua-green hair, and her eyes shine with blue light. As a High Priestess, she primarily wore a white dress with white, green, and blue jewels.

Darnasus was also the city of the Night Elves and also the name of the factions of the Nigh Elves that survived the Great Sundering. The Temple of the Moon in the Darnassus was the manor temple dedicated to the Goddess Elune and also the seat of government in the Darnassus and Teldrasil.

"Twin Tailed Comet... even the Moon Goddess is disturbed by the visions of the possible future that is coming, yet the appearance of the Twin Tailed Comet changed many things... Maybe for the better, maybe for the worse, but the time when the two civilizations long separated would become connected once again..."

She whispered as she received a vision from the Moon Goddess Elune as she continued praying to her Goddess. In the end, everything would play according to the will of the fate, they would only need to follow through it...

***

Similar occasions happened all around the entire Azeroth, where the beings of considerable power and wisdom received the appearance of the Twin Tailed Comet as an omen of something happening and the tide of change that was coming. 

Be it the powerful Archmages and Magisters, or even the other Dragonflights that took notice of the Twin Tailed Comet that fell on the southern Azeroth. However, when someone attempted to investigate the Twin Tailed Comet, everyone was repulsed by the overwhelming power radiating from it.

For many, this was rather unnerving because it represented the great unknown and for some it was good omen, because some could sense that the Twin Tailed Comet would bring the new age to the Azeroth.

For the other Dragonflights, of course, the most puzzling event was the disappearance of the Bronze Dragonflights that were sealed in their caverns of time by the barrier that was so strong that it seemed to be powered by the world itself.
