Short history:
Onyxia
Onyxia was the daughter of the mighty dragon Deathwing, and sister of the scheming Nefarion, Lord of Blackrock Spire.
Onyxia even assumed an alias once used by her father - the title of the royal House Prestor.
Onyxia resided in a fiery cave below the Dragonmurk, a dismal swamp located within Dustwallow Marsh. There she was guarded by her kin, the remaining members of the insidious Black Dragon Flight.
Nefarion
Nefarion was Onyxia's brother and the son of Deathwing.
He recided in Blackwing Lair, at the very height of Blackrock Spire.
At the mountain's peak, Nefarian had once begun to unfold the final stages of his plan to destroy Ragnaros once and for all and lead his army to undisputed supremacy over all the races of Azeroth.
More than ten thousand years ago, the black Dragon Aspect, Neltharion, began a quest to reign supreme over his fellow dragons and thereby dominate Azeroth.
Before Deathwing, as Neltharion came to be known, could achieve his goal, the other Aspects drove him into hiding.
The rest of the black dragonflight continued his foul work.
Hated and hunted for its evil deeds, the black flight dwindled, and at first Deathwing schemed to bolster its ranks.
In time, however, his agents began experimenting with other dragonflights to create a new and mightier breed of dragon.
The resulting experiments gave rise to a powerful and terrifying new breed:
The Twilight Dragons.
These malefic dragons were believed to be destroyed after an attack on Grim Batol.
But a new clutch of twilight eggs was recently discovered within the Obsidian Sanctum, the black dragonflight's domain in the Chamber of the Aspects.
Azeroth's heroes attempted to destroy the brood once and for all to prevent the dark future that had been set into motion.

Deathwing - The Cataclysm:
Deathwing the Destroyer had been brooding in Deephome, the elemental plane of earth, for some time.
As he regained his strength and was patched back up by the denizens of the plane, he prepared for his assault on Azeroth.
With cataclysmic force, he burst through the ceiling of the elemental plane and brought destruction to Azeroth.
Nearly all areas of Kalimdor and the Eastern Kingdoms were affected by the eruption.
The Barrens was cleft in twain, with an enormous volcanic fissure splitting it into two different zones.
Orgrimmar was destroyed, prompting Garrosh Hellscream not only to re-build the city, but to voraciously expand the Horde's territories.
The Desolace shoreline was cracked open, allowing water -and life- back into the zone.
Auberdine was flooded and destroyed, forcing the Night Elves to move north. Everything and everyone was affected.
Deathwing's great Cataclysm had significant effects on not only Azeroth, but on the races that inhabit it.
Especially some groups that would normally not seek help from other races.
The first race were the Goblins.
The goblin home island of Kezan had an active volcano erupt under it, prompting a Trade Prince to cheat his fellow goblins into being sold into slavery while trying to escape the island.
After their ship got accidentally involved in the middle of an Alliance-Horde sea battle, the Goblins found themselves washed onto an island off the coast of Kalimdor fighting unknown enemies and joining unlikely, but familiar allies.
The second race were the Worgen.
The reclusive residents of Gilneas, locked behind the Greymane Wall for a decade, had found themselves suddenly exposed for what they really were.
Having summoned the ferocious Worgen race during the Third War to combat the Scourge, the Gilneans found themselves quickly overwhelmed by the creatures, and the curse that spawns them spread unchecked throughout the kingdom.
Assaulted by the Forsaken, moving southward to claim the kingdom for themselves, the transformed Gilneans found themselves in need of two things:
A cure, and a hand.
With the night elves promising to aid their lupine allies, the Worgen were welcomed into the Alliance.
Deathwing not only sundered Azeroth. He also brought the Elemental Planes closer to Azeroth.
In many places, the planes are pushing through to terrestrial Azeroth. Ragnaros the Firelord, lord of the elemental plane of fire, has been seething from his defeat at the hands of 40 adventurers and has brought forth his fiery wrath on Mount Hyjal.
The Abyssal Maw, the elemental plane of water, has been raised along with the Lost City of Vashj'ir, Lady Vashj's domain, and with it a strange yet unseen sentient race.
And Deepholm has been thrust through the planet's crust by Deathwing's eruption into the land of flesh.
The Cataclysm also has brought back forces previously absent in Kalimdor and the Eastern Kingdoms.
Malfurion Stormrage has returned from the Emerald Dream to combat Ragnaros.
The Titan stronghold of Uldum, long obscured from view by technology, has become visible since the machinery that shielded it was destroyed, and within it may contain a Titan superweapon, or new allies.
Grim Batol, Deathwing's former place of imprisonment, is now reopened in the Twilight Highlands east of the Wetlands, where he raises his new Twilight Flight.
Meanwhile, Horde and Alliance tensions rise.
Garrosh Hellscream's temper rages unchecked through the Horde, and Thrall's ability to rein him in lessens with each passing day.
As he pushes to expand the Horde's holdings on both continents, battles rage.
The Forsaken march on Gilneas, the last remaining human kingdom in the Lordaeron region.
With everyone having left a piece of themselves in Northrend, even a tenuous peace may no longer be possible.
