Chaulssin

Chaulssin was a drow city in the Underdark. To some people it is also known as the City of Wyrmshadows. Chaulssin lies beneath the northern Rauvin Mountains. It overhangs a extremly deep abyss and cold winds howl permanently through the city. It rests upon a great spar of stone. After it was conquered by Shadow dragons and ruled by their descendants the city was partially brought into the Plane of Shadow. Tendrils of shadow-stuff winds all the time through the city and deadly shadow creatures haunts the streets. Sometimes whole quarters vanish into the Plane of Shadow and reappear years later.

Due to its remote location and its little known history Chaulssin is largly unknown to most inhabitants of the Underdark, let alone the World Above. This fact made it a perfect stronghold for the secret brotherhood of the Jaezred Chaulssin.

In the time of the War of the Spider Queen it was only a faint shadow of its former self. Most of the city stood empty and was only patrolled intermittently by tribes of Dark bears or claimed by small bands of Shadar-kai. The zekylyn lived alone in the upper reaches of the city's great galleries. There they trained under the watchful eyes of the Patron Fathers. The zar'thra'rin claimed the lesser tunnels of Chaulssin for their own, where they hunted the interlopers from the Plane of Shadow and the surrounding Underdark. They were organized in wolfpacks, dominated by the strongest male. The ilharen'quarthen dwelled in the heart of Chaulssin. They were the female concubines of the Patron Fathers and lived in lavish arpartmens surrounding the great lair of Patron Grandfather Mauzzkyl Jaezred. The other Patron Grandfathers visited their concubines in Chaulssin regularly, for each of them had only a handful of females with them in their respective cities.

History
Chaulssin was once a drow city until the Jaezred Clan conquered it and enslaved the inhabitants more than 1,500 years ago (measured from 1372 DR). This clan was a clan of Shadow dragons and they ruled for centuries. They mingled with the drow and created a slave race of half-drow and half-dragons. These slaves overthrow their masters and killed most of the dragons. Today the city is the headquarter of the infamous Jaezred Chaulssin, an organisation of powerfull assassins and worshippers of Vhaeraun.

Chaulssin got its title City of Wyrmshadows in the Year of Shambling Shadows in -221 DR, when shadow dragons of Clan Jaezred conquered the drow city and enslaved its inhabitants. In the following centuries the dragons brought the drow nearly to extinction and twisted them into creatures of shadow, they even mixed with them and created wyrm-spawned offsprings. All the while they tried to bring the city itself into the Plane of Shadow.

This changed dramatically in 634 DR (Year of the Darkspawn), when the shadow dragons of Clan Jaezred were overthrown by their own half-drow/half-shadow dragon progeny. These socalled Zekylyn had mastered powerful planar magic in secret while purporting to serve their masters. One of the few dragons who could manage to escape was Haernivureem, also known as Shimmergloom (after that he conquered Mithril Hall but was later slain through the hand of Bruenor Battlehammer). The rest of his clan were slain and reanimated as spectral creatures. The new rulers of the city began to rebuild it and used the wealth of the hoards from the dragons, which they had themselves plundered from the forefathers of the new rulers. In this time arrived also drow missionaries from Ched Nasad, Jhachalkhyn and Menzoberranzan, who tried to preach the word of Lolth but the Chaulssinyr patriarchy rebuffed them repeatedly.

Exile in the Plane of Shadow
In 734 DR (Year of Visions) appeared Vhaeraun to the leaders of Chaulssin and revealed to them that Lolth had decided to punish them for their defiance. To accomplish that, the ruling council of Menzoberranzan had dispatched a massive army to conquer the city. The patriarches of the City of Wyrmshadows chose to withdraw rather than make a suicidal stand. They opened portals to the Plane of Shadow and left the city. When the drow arrived a few days later they found only an abandoned city wrapped in the coils of the Shadow Fringe. The monsters from the Plane of Shadow pressed on them and the Menzoberranzanyr suffered heavy losses. Since there was little to show for their expedition they decided to claim victory and retreated, believing the flight of the Chaulssinyr was due to the might of the Spider Queen. The former inhabitants of Chaulssin encountered all manner of dangerous creatures on the Plane of Shadow, but at least no hostile army intending to kill them. They walked for miles through the Plane of Shadow and reached the abandoned lairs of their draconic ancestors from the Jaezred Clan to claim for their own. Here they began to built the Shadow City of Chaul'mur'ssin. But it was a hard time for the inhabitants until they could establish a real foothold in the Plane of Shadow. They changed in doing so and the populace gave up a large measure of its extraplanar Prime nature. They got stronger over the time and became a threat to other planar interlopers, like the scions of Clan Malaug, and to a lesser extent the Shadovar of Thultanthar.

A new vision revealed the priesthood of Vhaeraun in 792 DR (Year of the Crimson Thorn) that the leadership of the Chaulssinyr had been infiltrated by the maulaugrym. Only at the cost of many lives and the collapse of the city’s partriarchy were the shapeshifters finally unmasked and put to sword. In response the Church of Vhaeraun assumed power and founded the House Jaezred, an elite brotherhood of assassins trained to ferret out and kill shapeshifters. Thorugh this the conflict between Clan Malaug and the Chaulssinyr waxed and waned, with neither gaining permanent advantage. But the zekylyn learned from their enemies how to split their dual natures and alternate their forms between drow and dragon, creating so the first drow-dragons. House Jaezred earned through the stealing of this sectets from their enemies the respect of all Chaulssinyr and the leaders of the house threatened to eclipse the authority of the ruling Vhaeraunite priesthood.

Return of the Shadowkin
To avoid civil strife the patriarchs of House Jaezred agreed to return to Faerûn. There they would hold dear the debt of the Chaulssinyr to the Masked Lord and work to undermine the rule of Lolth. But this was also the start to distance themselves from the Masked Lord and his followers. In 1136 DR (Year of Shadowkin Return) House Jaezred returned to Chaulssin, where they established the House of Hidden Masters in its heart. There they started to call themselves Jaezred Chaulssin. The City of Wyrmshadows was a perfect place for a base of the leadership, but dangerous to raise the next generation of assassins. The parton fathers decided to establish fosterages in guise of minor noble houses in seven drow cities ruled by followers of the Spider Queen. This should have happened in Ched Nasad, Eryndlyn, Karsoluthiyl, Jhachalkhyn, Maerimydra. Sschindylryn and Menzoberranzan. But Menzoberranzan proved to be resistant to infiltration and so Dusklyngh was chosen instead as the seventh fosterage. Jaezred Chaulssin also established half a dozen smaller fosterages throughout the Underdark where Lolths power was minor but drow could walk openly, like in Skullport or Sshamath.

Threat from the Shapeshifters
During the Harpstar Wars (1182 DR – 1222 DR) the shapeshifters of Clan Malaug captured a spy of the Harpers. His spy had previously explored Chaulssin and so Clan Malaug learned of the return of their enemy to Faerûn. Only their own losses in the war prevented them from attacking the City of Wyrmshadows and they needed time until 1241 DR (Year of the Lost Lady) to get strong enough. In this year a raiding party of malaugrym managed to kidnap a pregnant concubine of the Patron Grandfather. The assassins of Jaezred Chaulssin tracked them down and killed the interlopers before they reached Castle Malaug, but the concubine vanished during the fight.

The War of the Spider Queen
After centuries of secret activities and infiltration of the drow cities ruled by Lolths followers the year 1372 DR (Year of Wild Magic) promised to be the most important one for the plans of Jaezred Chaulssin. Now they saw the opportunity to struck several Lolth-ruled cities at once. They had their hands in the plots which brought stone fire bombs to Ched Nasad and caused the destruction of the whole city. In Eryndlyn they brought the followers of Vhaeraun and Ghaunadaur together against the Church of Lolth and decimating the ranks of her followers drastically. Smaller strikes in Dusklyngh, Jhachalkhyn and Karsoluthiyl weakened the hold of the ruling Matron Mothers and helped the male-dominated merchant houses to gain influence. However in Maerimydra were their plots crossed, when Kiaransalee’s followers claimed the city for their own. In Menzoberranzan the invasion of the duergar armies of Gracklstugh and the tanarukk of the Sceptered Legion failed. Since the end of this war the patron fathers have begun to cement their control over the ruins of Ched Nasad and their influence on the factions of Eryndlyn. Also they got money of the merchant houses under their control in Dusklyngh, Karsoluthiyl and Jachalkhyn.

Galleries of Shadow
The Galleries of Shadow encompass the lesser halls and chambers of the city linked by tunnels. They are not considered part of the House of Hidden Masters. Packs of Zar'ihtra'rin, companies of Dark bears and small bands of Shadar-kai consider it home. Interlopers from the Plane of Shadow are not uncommon where the Shadow Fringe is close.

Howling Abyss
Chaulssin rests on a huge spare of stone at the edge of a great chasm in the earth. It is known as the Howling Abyss which extends at least three miles above the city and more than seventeen miles into the depths. Winds with the force of Hurricanes buffet Chaulssin relentlessly, threatening to sweep away anyone that dares to show his face on the city’s battlements or attempts to fly through the chasm. The Howling Abyss is home to dangerous creatures, like Belkers and voidwraiths. The spectral-shadow dragons, reanimated undead of the former rulers of Clan Jaezred roam through the city they once ruled und defend it against interlopers.

House of Hidden Masters
At the heart of Chaulssin lies the House of Hidden Masters. It is the chapterhouse of the Jaezred Chaulssin and resides in what was once the city’s largest temple to Lolth. In the center of the temple lies the opulent lair of Patron Grandfather Mauzzkyl Jaezred. The walls hung with tapestries of woven shadowstuff that depict distorted images of scenes long forgotten. The floor is piled high with rarnished coins varying mintage design. Glistening onyx embedded with beljurils form the arched ceiling. The lair of the old dragon is surrounded by lavish apartments of the concubines (known as ilharen'qarthen). Each of them resembles a small version of the main lair and is heavily guarded, for the Patron Fathers do not trust each other to steal a rival favored concubine. The inhabitants of each harem largely govern themselves when the masters are absent. But if worship of other gods is unearthed it will be ruthlessly stomped out.

Shadow Fringe
The City of Wyrmshadows exists partially in the Plane of Shadow. Tendrils of shadowstuff constantly wind through its ruins, ebbing and flowing with the pull of some erratic, unseen moon. With this deadly creatures of the Plane of Shadow cross the planar borders and haunt the streets. From time to time whole quarters vanish into the gloom entirely and reappear years later.
