Kabal of the Spectral Form (updated homebrew)

'Remember my kin, that silence is golden. Those who listen, will learn, and that knowledge is power. Choose your words carefully lest they betray you and lead to your own undoing.'
- Kha'lir: warden of whispers

The Kabal of the Spectral Form are, as their name suggests, the unseen ghosts of the dark city. Their existence is only known to few, more a rumour, a movement in the corner of peripheral vision. For the Spectral Form are the most adept spy network that this infamously deceptive city has to offer. It is even whispered in the darkest corners that they sold the information that enabled Vect's would be assassins to gain access to him. There is little that occurs in Commoragh or indeed real space that does not reach the ear of it's Overlord Kha'lir; once a disgraced messenger, he now commands the network that is said to hold secrets that even Vect would not wish to come to light.

The Kabal has no central spire, instead a series of safe houses known as the vaults are enclosed in the most secret paths of the webway and hidden throughout the city.
These great libraries house records of unimaginable depth, detailing both the important names, wars and locations of the galaxy among seemingly insignificant facts, such as the contents of an inquisitor's bedside cabinet or the colour of a rival Archon's throne. The deepest corners of the most secure vaults house relics of arcane power, tools of destruction not seen since the Fall. Any lucky enough to discover the whereabouts of one of a Vault may be tempted by it's promises of knowledge or riches, but only the foolish would attempt such a theft. For the Vaults are guarded by the foulest and most sinister of the Kabal and their allies, and myriad traps lie in wait, threatening fates far worse than death.

When conducting realspace raids, the Kabal uses tools of disruption, misinformation and mis direction. An enemy may seemingly fend off a full frontal assault of screaming wych allies, lumbering mutants or teeming mercenaries only to discover that their leaders have been hung, skin flayed, from the rafters, or their defence systems have been reprogrammed to target them. Orders are intercepted and replaced and in the confusion, the Spectral Form strikes at the most vulnerable targets.

The purpose of many of these raids in to add to the wealth of the Vaults, building the already considerable power and knowledge of the Kabal even further. At the centre of this web sits Kha'lir, the Warden of Whispers, his sinister plans slowly coming to fruition...

[B]Founding:

Before Vect's rise, Kha'lir was a young messenger in the servitude of a moderately influential and powerful noble family known as House Drychal. His masters were of a particularly cruel disposition, whimfully beating, torturing or executing any who did not live up to their standards. Kha'lir became a master at being both unseen and unheard, appearing only when he was needed and seemingly disappearing directly afterwards. As his servitude continued, his hatred and resentment grew. As a messenger, he became privy to significant and sensitive information; the layouts of the inner chambers of many nobles and the state of the shifting alliences and rivalries between them. When he heard whispers of an imminent uprising from a low ranking slave he began to take an interest. Aiding Vect with information and building alliances with many other messengers and agents through the dark city, he laid the foundations for many of Vect's early triumphs. As soon as he had solidified his position in the coming times, he killed his former masters with ruthless efficiency.

[B]Notable Raid (example)

Attila system: raid carried out over 1 full Terran year. Reports of disappearances and malfunctions throughout an imperial forgeworld. Military forces in disarray from false communiques and lack of leadership as all high ranking officials reported as missing. Multiple attacks in more rural areas drew out much of the military strength that was already in disarray following a series of often conflicting orders. When they returned to the cities, the entire population had vanished, with only remaining officer's bodies found mutilated.

[B]Relation to other races:

Unlike many of their kin, The Spectral Form learn a variety of languages and customs of other races, allowing them to maintain a network of informants and assassins. Although not directly allied to anyone but themselves, they will trade in information and relics where they see it as more practical than simply stealing the item and murdering it's previous owner.

[B]Kabal Culture

Induction into the kabal is grueling to say the least. The swift delivery of information and intuition are highly prized in it's potential members. A common ritual is for a sybarite to cut out the tongue of the candidate and give him a spoken message to deliver to a location of the Dark City. The path may be littered with other aspirants who will try to murder, cripple or other wise halt their progress until completion.
The heirarchy of the kabal is fluid and ever changing, all members of the kabal are given the same rights and protection but each member will only know a small token of the secrets of the Spectral Form, pieces of a wider puzzle that Kha'lir alone can solve.

[B]The Vaults

The vaults act as safehouses for relics and vast stores of information. The entrance to a vault is always concealed and unassuming; a wall in an arena, behind the curtains of an abandoned manse or a trap door in the basement of a drug establishment may all hide gateways to these labyrinthine structures buried in sub realms of the webway. At their centre are the great libraries; fortress complexes that defy the laws of physical reality. Lining the passages of these places are the sometimes still living remains of the enemies of the kabal, contorted into grotesque forms of art and framed for the appreciation of their tormentors. Traps of all kinds are littered throughout and the most valuable treasures are guarded by numerous warriors and beings, creatures of more malicious intent even than Mandrakes, assassins, and incubi are all to be faced by any potential unwanted lurker. To face these tasks is to be tested to the fullest both physically and mentally, for The Spectral Form have neither mercy nor sympathy for those who seek their life's work.

[B]Alliances and Associates in The Dark City

As highly pragmatic and versatile as their Overlord, the kabal has a more open approach to partnership with others in the quest to expand their knowledge:

[I]The Cult of the Shadowed Talon

Led by the succubus Tattu Shadowform, this Wych Cult specialises in the art of the stealth kill. It's membership is small but visitors to the arena sit in anticipation, eagle eyes still searching in vain for a sign of the warriors about to dismantle their latest victims. It is said that whole armies of these skilled gladiators can appear as if from nowhere at the weakest points of an enemy army.

[I]The Heralds of Agony

These ace fighter pilots have come under the permanant service of the Spectral Form, which provides them with ample payment and gives them plenty of opportunities to practice their deadly skills in realspace.

[I]Eyrie of the Last Breath

These scourges have become synonymous with Kha'lir's forces, fiercely loyal to him since the early days of Vect's rise. Now the Kabal sponsors them directly, though this is known only to few, worthy kabalite warriors are chosen to become the ultimate symbol of the Kabal's influence. They are given anything and everything their dark hearts desire, for information is the life blood of the Kabal, and the Eyrie has specialized not only in carrying messages but intercepting them too, sometimes replacing the original to spread misinformation and confusion
