Jaezred Chaulssin

The Jaezred Chaulssin was a secret patriarchal organization based in Chaulssin consisting of skilled shadow dragon-blooded drow assassins.

Base of operations
The Jaezred Chaulssin were "based" in the ruined drow city of Chaulssin, from which they got their name. However, they also infiltrated minor houses in many drow cities, which they used as bases of power, called fosterages, and places to raise their young. These cities were, namely, Ched Nasad, Dusklyngh, Eryndlyn, Jhachalkhyn, Karsoluthiyl, Maerimydra, and Sschindylryn and, as of 1469 DR, Menzoberranzan with an fosterage of about 140 members. Apart from these, they kept six minor bases in settlements like Skullport or Sshamath that were not (primarily) ruled by Lolth but allowed drow to walk freely.

Activities
The goal of the Jaezred Chaulssin was to rid the drow of the tyrannical rule of Lolth and her priestesses. In order to do that, they believed that drow society had to be shattered so that they could turn away from Lolth. The Jaezred Chaulssin could then rise as the secret masters of the drow. They were fully aware that destroying the system under which the drow lived would make them suffer weakness and enslavement for a time measured in centuries, but were wiling to risk it to "save" their people.

Members
The Jaezred Chaulssin was made up of drow with shadow dragon blood, namely the following types:
 * zar'ithra (shadow draconic drow)
 * zekyl (half-shadow dragon drow)
 * draa'zekyl (drow-dragon) (the eight Patron Fathers)

The Jaezred Chaulssin were not particularly numerous, but their power belied this fact. The zeri'ithras' draconic blood and their ties to the Plane of Shadow gave them stronger bodies as well as some magical abilities (like faster movement, resistances to cold or nonmagical attacks, some innate spells). The zekyl showed even stronger bodies and the ability to breathe shadowy fumes that sapped the abilities of their targets (they were immune to their own and each others' breathes themselves). Unlike other half-drgons of their size, the zekyl sported wings that allowed them to fly. They could fly faster than they could walk.

The Jaezred Chaussin were followers of Vhaeraun, but over a few centuries they began emphasizing their faith less and less. Still, the death of Vhaeraun in 1375 DR, alongside the Spellplague, was such a heavy setback for them that they were forced to rebuild their strength for an entire century.

Organization
There were seven Patron Fathers of the Jaezred Chaulssin, led by the Patron Grandfather. Each of the Patron Fathers was a drow-dragon, a half–shadow dragon drow who had divided their heritage into separate dragon and drow parts, thus gaining the ability to take either form. They had concubines, collectively called ilhare'quarthen, in both their home cities and Chaulssin. The majority of them were in Chaulssin because the Patrons couldn't risk keeping many in Lolth-ruled cities.

The Patron Fathers were served by the Velves ("blades"). The seniormost Velve was the Ortho'Velve ("Anointed Blade"). The next in rank were three Ust'Velves ("First Blades"), five Draat'Velves ("Second Blades") and so forth.

History
House Jaezred was founded in 792 DR when Clan Jaezred's Church of Vhaeraun found that that the Chaulssinyr leadership had been heavily infiltrated by malaugrym. The house was an order of assassins created to find and destroy any shapeshifters of Clan Malaug infiltrating the group.

House Jaezred set up base in Chaulssin first in 1136 DR to establish the House of the Hidden Masters and came to be known as the Jaezred Chaulssin.

In 1241 DR, Clan Malaug kidnapped the pregnant mate of the Patron Grandfather. The Jaezred Chaulssin were able to kill the kidnappers but the female drow-dragon vanished. The missing offspring was discovered in 1358 DR north of Amphail under the name Nurvureem but the Jaezred Chaulssin opted to just watch and wait to see if she became a threat.

During the Silence of Lolth in 1372 DR and 1373 DR, the Jaezred Chaulssin chose to strike and implement their plans to take down a number of Lolthite cities. They provoked uprisings in Eryndlyn, Dusklyngh and Maerimydra (which was unexpectedly lost to followers of Kiaransalee). In Eryndlyn, the Jaezred Chaulssin motivated the followers of Vhaeraun and Ghaunadaur to work together, so they can destroy the rulership of Lolth's priestesses, which they did. A series of strikes in Dusklyngh, Jhachalkhyn and Karsoluthiyl resulted in creating a power vacuum that mostly male merchants filled who then funneled money back to the Jaezred Chaulssin. The Jaezred Chaulssin also plotted against Ched Nasad and Menzoberranzan. They provided the stonefire bombs that led to the destruction of Ched Nasad by incinerating the calcified webbing on which the city was suspended. As of 1469 DR, Ched Nasad's ruling council, which was obliged to make concessions to the Jaezred Chaulssin, was considered an abomination by the one of Menzoberranzan because the males of the leading House Teh'Kinrellz, controlled by the Jaezred Chaulssin, had power rivaling and/or exceeding the females' power.

Shortly after the fall of Ched Nasad, the Anointed Blade, Nimor Imphraezl, brought together a number of allies, including Crown Prince Horgar Steelshadow's duergar army of Gracklstugh, the Scourged Legion of Kaanyr Vhok, and the drow House Agrach Dyrr led by the Lichdrow Dyrr. He secretly led them in a siege on Menzoberranzan. Although his forces succeeded in defeating the city's Army of the Black Spider, the siege ultimately failed when Lolth returned and the Silence of Lolth ended, allowing the city's priestesses to turn back the invaders.
