|Period||10 - 25|
In the Dawn Era, the Turgon's northern half became the stomping grounds for lizard-like humanoids known as the Graagvrii. The next to make a permanent home here were wood elves. These were a ex-Covenant soldiers that had fought in the Demon Spawn War. They settled in the island's south, in a heavily wooded interior called Lossëhelin. Kriavian Elves were the next to arrive on Turgon. They arrived in the Horgon Era as Gwildath colonists from the world Kriav. They would be the cause of a conflict that would forever change Turgon, turning it into a demon bastion, a foothold on a mortal world ruled by a demon lord.
Generally, the Kriavian Elves, with holds along the coasts, looked down upon the island's Graagvrii. They viewed them primitive and savage. They also didn't like their might makes right thinking, ideals ingrained in those worshiping Semuanya. Turgon's wood elves viewed the lizardfolk on more equal terms. They had been through enough wars with them that it was better not to give their neighbors a reason to unite.
In the ninth year of the First Epoch, the four great tribes of upper Turgon were given a reason to unite. Policies of Nénharma, a Kriavian Elf city-state, were proving very effective at reducing their populations south of the Cinnadan mountains. These southern living lizardfolk, what the elves called the "free lizardfolk", were outside the four main tribes of northern Turgon. They were a way of keeping a presence in the wetlands and rivers of the south while being "officially not part of the four tribes of Coremeen".
The Graagvrii and Vedrii united under the Tetramord Pact. The size of the threat was such that Lossëhelin's wood elves and their coastal dwelling neighbors, the Kriavian Elves, reluctantly joined forces under the Phael alliance.
For the first three years of the war, they battled in the Ashemhorn valley. The Phael, in command of the Turgon Aeries, were behind strong defenses. These were centered on ancient mountain redoubts that in times of peace served as monasteries for monks.
Making no progress down the valley, the Tetramord went east, along the coasts and attacked Celanil. They were harried along the way by wood elves lurking in the tree tops, sniping and assassinating to great effect. In the Year 13, Celanil fell to the Tetramord. They suffered so badly getting here, including three years battling the forces holed up in the Turgon Aeries, that their commanders could not contain their soldiers thirst for revenge. They reduced the city to ruin, slaughtering all of those captured.
After Celanil was sacked, Tetramord armies marched west through Lossëhelin, home of the island's wood elves. It took two years to cut a path through, requiring strong garrisons and fortifications to be left in their wake. Attacks on their supply lines were a constant problem. The battles with the wood elves were often one's of deception, ruse and guerrilla tactics. Tetramord, a mix of Graagvrii and Vedrii, were adept at these sort of things, yet nothing on the level of Lossëhelin's wood elves; ancestors to the Angrods.
In the Year 16, the next to meet the Tetramord onslaught was the city-state Nénharma. General Shearmor, a brutal Vedrii, rode up within speaking distance of the city. To his embarrassment, he nearly lost control of his mount; a fiendish rage drake named Bilsick. The general thought he heard laughs from the walls of his enemies, wondering if Bilsick's unruliness the work of elven trickery; never considering that his evil sentient mount simply craved elven meat, and had no interest in seeing a parley. After six months of siege works, Shearmor offered Nénharma's besieged safe passage. He warned what would happen if they continued to resist, looking back over his shoulders in the direction of Celanil. Cut-off from reinforcements, facing a force of nearly 20,000, Nénharma took the offer. When outside of the city, and on their way to the elven stronghold Finwë, in response to what happen before the walls, General Shearmor ordered an attack on the refugees. Thousands of civilians and soldiers were killed. After this treachery, Phael would begin using similar tactics on their enemies.
The war dragged on after his, with enormous casualties on both sides. Quarter was rarely given. The war shifted in favor of the Phael in the Year 21. When the Tetramord front was pushed back, the Phaels passed through the ruins of their former strongholds and cities. At the sight of the ruins and bones of their comrades, the elves grieved for the losses. The mourning turned to anger and revenge when they learned of the true horror that happened to the fallen. The bones were scatted and broken, as if wild animals had eaten them, and divination spells revealed that many of their kin were consumed while still breathing. The Phael declared that no mercy would be given to the Tetramord, the civilizations of the lizardfolk must be exterminated. Nearing the wetlands of Coremeen, the elves met stiff resistance. Phael wizards and priests conjured minions to assist them. Some refused to work with those that conjured them, telling them that their methods were evil. The conjurers turned to those with less scruples. They figured that sending evil against evil was as good a choice as any, if either died, it mattered little.
In the Year 23, a rift was opened in the Web of Magic. Seeking the aid of a dozen or so vrock, the spell ruptured the fabric of the Web, forming an inter-system rift. This was small at first, but soon expanded under a Zone of Great Magic. This then turned into a Cascade, and the outcome was horrific. The rift, what became became known as the Ungorth Reddik Road, expanded to nearly a hundred feet in diameter. It led to one of the worst possible places of the Abyss, the walls of Ungorth Reddik. This sinister place on the world Abyssm is a major citadel of Demogorgon. This demon lord's legions poured through the gate, wrecking havoc across Turgon. The Phaels beat a hasty retreat. The demons grew in numbers and began to overwhelm the defenders of Turgon.
At Solendë, we fought back to back with our former enemies. Our hate of each other was forgotten, we fought as an elven and lizardfolk army against wave upon wave.
- Helendë, historian of Spirachiln - "A Common Foe"
The island's elves, wood and Kriavfahliil, headed for the coasts, taking ships and using magic to escape lands quickly falling to the demons. This escape, the Turgon Exodus (13 - 25), led to many going north across the Mephigax, settling in the High Wood Country. Another group, the people of Tasartir sailed east re-settling in the Pipe Home region. The Tetramord suffered an even worse fate, a painful death or sent in chains to some distant slave markets, destined to serve the whims of some demon.
