Xorvintroth

Xorvintroth was an ancient dragonborn city of Abeir, the sister-planet of Toril.

"To deny the radiance of the stars is to walk forever in darkness."

- An inscription written in draconic, found within a shrine in Xorvintroth.

Description
Xorvintroth was several miles wide in diameter. Its architecture comprised a network of viaducts and colonnades that wound around and connected its narrow and angular buildings. They were constructed from several green-hued minerals, including what appeared to be jade, and a translucent, viridian stone that appeared as an alien form of stained-glass. They featured intricate and over-adorned architecture, utilizing no right angles but rather forms that arced and crested over other like static waves.

Tableaus and engraved murals of daily life in Xorvintroth could be found throughout the city. They often depicted poised dragonborn scholars dressed in elaborate robes. Aspects of these murals flickered and shifted when not viewed directly, but remained static when focused upon.

After explosives were detonated at several sites throughout the city, it became encased in a protective sphere made of green, glass-like stone. This barrier had to subsequently be punctured before it could be accessed once again.

Technology
The scholars of Xorvintroth developed devices that could harness raw magic, a source of infinite arcane power that could be extracted from the Far Realm. This power was unaffected by the constraints of the Weave ―the mystic force that governed the use of magic on Toril―which itself was not present on Abeir. The power taken from the Far Realm was channeled through conduits throughout the city and subsequently stored in self-contained devices. These 'arcane storage batteries' were used to power the fantastic machinery and magnificent devices dreamt up by the Abeiran dragonborn artificers.

Xorvintrothian inventors developed crystalline containers that were capable of other forms of energy as well, including pure lightning and fire.

The city itself was protected by a series of wards that prevented teleportation within or out of its borders.

Atmosphere
"Those willing to deny themselves the radiance of the stars would be better to pluck out their eyes and cast them away."

- A more accurate translation of the aforementioned shrine's inscription.

The residual Far Realm energy that permeated Xorvintroth caused mild visual and auditory hallucinations to some that traveled within. Trespassers may have seen phantasmal darkness pass over them, heard faint and indiscernible clicking sounds, or witnessed the twinkling of malicious stars across the ceiling. This alien force, combined with the debilitating surrounding chill could be exhaustive for anyone not immune to their effects. It also inspired paranoid and delusional fears in the minds of many that entered within.

Etymology
The city was named after xorvintaal, the ongoing and ever-present contests of will and power between the dragons and dragonborn of Abeir.

Geography
After bring transported to Toril, Xorvintroth lay beneath a large, crater-like valley in the Spine of the World mountains, three days' travel east of Easthaven. Over the years it had become blanketed with so much snow and ice, that only its tallest structures could be seen.

Geographical Features
A massive crevasse formed near the ruins of Xorvintroth, within which formed a spectral echo of the destroyed city. While a layer of ice formed above the chasm it could easily be cracked with enough pressure or weight above.

The ruins of Xorvintroth were accessible by means of long ice cave that opened out the side of a mountain, or by the series subterranean tunnels dug out by a group of aberrant arachnoids. The underground tunnels were permeated with clouds of poisonous gas and corruptive energy that emanated from a mysterious source deep underground.

Government
On Abeir, Xorvintroth was governed by sect of elder dragonborn known as the Inquest. These "wise" rulers attained a form of immortality when after their bodies decayed, their consciousnesses were preserved in a shrine near the city's Chamber of Stars.

Defenses
Dragonborn artificers built into Xorvintroth an arcane safeguard incase the city ever faced true catastrophe. When triggered by a large enough event, Xorvintroth became encased in a massive dome of glassy, viridian stone.

Abeiran History
"Xorvintroth. That Which Survives. As the Great Mothers and Fathers wile away the eons playing their Great Game, our city proves to be the most valuable playing piece. Ne'er shall it be used. Ne'er shall it be lost."

- An inscription set at the base of a statue in the Chamber of Stars.

Xorvintroth was constructed millennium before the Era of Upheaval on Toril, a feat that required the labor of hundreds of dragonborn masons and laborers. The city became a destination for scholarly pursuits and arcane research, and grand telescopes were constructed upon its highest towers.

The city became imperiled however when the Inquest initiated research into the Far Realm, and opened portals to the aberrant plane of madness. Through their research the dragonborn scholars broke through the barriers of reality itself and trespassed into the alien reality of the Far Realm. Once within, they were granted them access to a source of infinite arcane power: raw magic.

Some unknown catastrophe threatened the city and many of its citizens attempted to flee. Their efforts were thwarted by the Inquest.

They attempted to construct a grand "bridge" that would allow the people of Xorvintroth to flee all fighting and settle on a new planet.

Torillian History
Xorvintroth lay dormant on Abeir until the Spellplague rejoined the planet with its sister-world Toril in the. The city was expelled from Abeir and transposed to Toril the depths beneath the Spine of the World mountains in coldest reaches of the North. The planar anomaly previously opened by the Inquest was transported to the rock beneath the mountains as well.

In the, a group of neogi aboard a deathspider touched down in the mountains near where Xorvintroth was buried, and abducted a group of goliath hunters as slaves. The neogi and their captured goliaths wandered into an area in Xorvintroth and were horrifically dismembered, and their remains strewn across the city's floor.

The Lost Goliaths
Evidence of the slaughter was found by the giff Lieutenant Prook and group of adventurers that went searching for the missing goliaths. They delved into one portion of the city but were unsuccessful in their mission, having been turned away by the horrors inside. Prook then began to assemble a series of bombs to completely demolish the ruins and destroy the extraplanar monstrosities that threatened Icewind Dale.

The adventurers planted Prook's explosives throughout the city and finally rescued Nararhak "Tree-Eye" and the other goliath hunters. After scrambling to a safe distance away, they detonated the bombs―believing they had buried the haunted ruins once and for all. Ironically, the explosives did not harm the city itself, instead triggering the magical failsafe that enveloped the collapsed city in a sphere of virescent stone.

Unfortunately for the goliaths of Wyrmdoom Crag, the returned goliath hunters brought with them some of the dark force of the Far Realm. Another hunter named Kaskur "Spearsong" led his own unsuccessful search party for his missing clansmen. Kaskur and his hunters inadvertently picked up some of the dark force of the Far Realm that lingered within Xorvintroth's ruins. Upon the hunters' return, Far Realm monstrosities like flying horrors and dolgaunts burst forth from their bodies.

The Red Wizards' Schemes
A short time after the goliaths were rescued from Xorvintroth, a group of Thayan operatives began excavations of the ruins. They operated under the direct orders of Thay's undead regent, Szass Tam. Szass Tam sought to take control of Xorvintroth's otherworldly technology for himself and bypass Mystra's laws of magic that limited the power he and all other mages of Toril possessed.

A band of Thayan warriors made the journey to Xorvintroth and soon recovered many strange and fascinating artifacts for their Red Wizard masters. They secreted in supplies to their excavation site by means of dogsled caravans that traveled across the snowscape and set up magical barriers that prevention intrusions by means of the ethereal plane.

An esoteric Sharran cult known as the Tenebrous Creed began poking around the ruins as well, in search of some long-lost entity sacred to them. A third group also ventured into Xorvintroth: a collective of adventurers and Harpers assembled by Lady Remallia Haventree of Waterdeep. After seeking out knowledge about the Red Wizards' schemes involving the Far Realm, they established a Harper safe house under the Hall of Arcanists.

Rumors & Legends
Former inhabitants of Xorvintroth were believed to haunt the city in perpetuity, continuously reliving the events of their day of destruction forever among horrors they released.

A tiny sculpture in the city portrayed the quirky traveler Fizban, an avatar of the platinum dragon Bahamut. He was depicted his trademark floppy hat and canary companions in tow.

Inhabitants
After the portals to the Far Realm were opened, Xorvintroth became overrun with aberrant and monstrous horrors, including gibbering mouthers, star spawn, and at least one skittering horror.

The cabal of dragonborn that doomed Xorvintroth arose after death as mindless ghosts from the Border Etherual, with blazing stars in the place of their eyes. These ghosts haunted the frozen necropolis, and the adjoining chasm that manifested a spectral version of the city. Spiritual echoes of the city's dead were doomed to enterally enacted scenarios in which they fled from these ghosts.
