The faction of Astaroth send an agent, a succubbus, to prevent the Angel from reaching his goals. The succubus, individually, is no match for the angel. So, she starts to weave her web of relationships. Unfortunately for them, she starts with the PC team. So, the representant of the followers of Astaroth, a succubbus named Laylah (meaning 'night' in Hebrew) must retrieve the serial killer (or utterly destroy it) before the Angel to prevent him from getting the corpse and the soul of this killer. But she is in no position to face the angel and his troups, as the angel is far more powerful physically than she is. So she is inclined to use rather her guile or some indirect actions involving humans...
She explains that she returned from the dead because supernatural powers invested her with a mission on earth: she has to assassinate a serial killer (who is jailed in the death row of the local prison) before an evil ennemy of her (supernatural as well) would free the killer, and hire him (using the assassination skills of this man for some evil deeds).
The succubbus doesn't say however that she intents to kill herself the man by drinking his soul, thus gaining his knowledge and skills; nor that the "evil ennemy" of her is actually an angel. (demons and angels are equally evil from human point of view in Kult, but she knows that humans have a weird predisposition to trust angels, which proves usually fatal to them).
So, in the player's introduction, the succubbus gains easily a firm grasp on the PC whom she is imitating the dead spouse (or girlfriend). But she still has to motivate others PC as well.
She tries to give each of them something they really want (wether something the need individually, or something they need as a group to conclude another part of the campaign). This is her "job" as a Succubbus to know the longings and desire of everyone and to play on it. In addition, she has enough magical power to get most things in the Illusion (or imitation good enough of the actual thing).
Sunday: an old woman, neighbour of a PC, during the evening mass, yesterday, saw an intense light inside the church (she was outside the church at some distance). None of the direct PC acquaintance went at the mass in this church. This witness (the old woman) is very talkative, and will spread rumour (strange things like this don't occur everyday in this town!). People who were in this church don't remember anything special, but have strange behavior, like if they were a little drunk (they are now under the angel's control).
Sunday, in the late evening: all the PC return home. They were abroad for some time (or this is a new city for them and they just arrived but are supposed to spend some time here).
The PC begin to have a strange feeling, like if someone singed cantics from far away, so muted that they are feeling it inside their head rather than actually hearing it. None of the people who stayed in town for the last few days seems to perceive this.
In the middle of the night, a PC who is awaken at that time could see a strange, intense light coming from a neighbouring street (but not the one which is just under his window). He cannot see anything: even if he goes outside of his house, the light disappeared before he could follow it in the streets.
A PC finds again, under weird circumstances, a long lost love, someone he really would die for but that he no longer can see (for a reason or another : she is using the appearance of a girl he was in love with but he never had, or of his departed young wife, etc...). She is naked, unconscious, and even more beautiful than in the PC's memories. [She is obviously the Succubbus, just created by a minion of Astaroth an still very weak]. Once awaken, she finishes to seduce the PC (At this moment, the Succubbus is very frail, she needs to drink souls to regain some power after her recent recorporalization. But she doesn't want to harm herself the PC [they are the operationnal team that she is wanting to use, so she prefers to let them harm the Angel (or die trying) rather than wasting them]. She seduces a PC with his dearest sexual/love fantasy, pushed to a level of satisfaction he never experienced before, and makes her home in his house. She answers as briefly as possible to any question. After that, she regularly brings new people that she kills there, and after, she wants the PC to dispose of the corpses. [she acts like some kind of vampire rather than anything else by that time].
Monday: The neighbour of a PC, a middle-aged woman, mother of 3 children, usually perfectly sane, is taken to the psychiatric hospital: last night she claimed to have seen the Face of God. She is extactic, and joyful. But, despite this, seeing God seems to be a traumatic experience: she gouged out her own eyes out of their sockets and thoroughly scarred her own face with her nails. Despite this, she is extatic and tells prayers continuously. [in fact this woman saw the succubbus who took an incarnation of an unbearable beauty, trying to conform to the idea the woman had of God. The succubbus wanted some informations about what the angel was doing, and asked to whis woman who attended the Sunday evening mass. The Succubus assumed this form, and once she had all needed information, she utterly destroyed her mind, to avoid being tracked down by the Angel].
What PC are seeing: police cars and an ambulance (all with sirens wailing) are gathering around the house of a neighbor, They are taking the mother of the familly who lives there. If PC are trying to see what happened in the house, they will just see blood everywhere. If they are listening at the radio or watching the TV, they will soon have local informations depicting this weird incident.
The PC still "feel" the cantics, just out of reach of their ears. In addition, some PC begin to have a semi-permanent headache, very unpleasant (this PC are the more reluctant to the influence of the angel who is very close from here: he remains in the crypt under the nearby church). Other PC begin to feel good, and to be unnaturally joyful (and that would take no effort to the angel to gain control upon them).
Tuesday: A man is heavily affected by the nearby angel and his artifact (the angel has a light sword a very powerful artifact made by a follower of Kether). The man under influence looses what remains of his sanity, loathe the sinners that surrounds him, and feels a compulsive need to cleanse the sin in the blood. So, he takes a firearm, climbs to the roof of the local church, and begins to kill everybody in the streets above. When he is arrested, he claims he did this because God ordered him to do so in his dreams. The next night, in jail, he commits suicide by striking repetedly his head on the concrete floor until his skull is crushed to death. Two other people from that side of the town, that day, are reported to have savagely murdered someone, or to have mutilated themselves because God ordered them to do so. Kether influence, even through an artifact, is too strong for those blind humans.
Event for the PC: a PC is going back to the house, he is saying 'hi' to a neighbor (or the postman, or anyone he knows from this city), when there the head of the man explodes, splashing everything with what used to be his brain. He was shot from the roof of the Church. Next bullet miss the PC by centimeters. After that, he better have to hide, or the next one could hurt him... Police arrives there in a few minutes, prevent people from crossing this streets. A police sniper shoot the man on the roof (destroying the shoulder holding the weapon), and he falls from the roof into the street. Despite the bullet and the fall, the man still tries to stand up.
After they have retrieved the seriall killer from the jails, the Succubbus disappears, and may come back later if she needs some more help from the PC. The PC who was charmed by her falls in a deep depression: having a love and sex affair with a succubbus is an utterly addictive experience. So, he looses all interest in sex with mortal women (at least for a few months or a few years), and needs weeks to recover from his depression, with the definitive loss of some Mental Balance in the process.
The Angel, in our world, is the leader of a paramilitary wing of the church (named The Purifying Flame) which is engaged as an independant party in the global fight in Metropolis. [The new preacher (Rod Helander) is a member of this paramilitary wing of the church and he is a mere puppet in the hands of Celerophon, the Angel].
The light which was sometimes seen in association with the Angel during the last days is the light sword of Celerophon. It's a unique artifact (a really powerful magical object, made by Kether, and given to this angel in retribution of cheer services by an officer of Kether). When it is wielded, every human seeing it is fascinated, will always follow its holder in a fight and will happilly give his life for his leader, the holder of the sword).
The angel is applying the following plan:
Whem she comes close to people, she senses their dearest and most hidden fantasy. If she finds the soul of someone with such a fantasy to her taste, she seduces him/her and realises this fantasy beyond his dreams. During the satisfaction of their sexual appetites, she drives her lover far beyond exhaustion, until he eventually dies.
Then, she drinks his/her soul and retains what she needs from it. This soul is now destroyed forever (or integrated and transfigurated inside those of the succubus, as she likes to consider) ; and she lefts only the empty shell of her dead lover.
The more souls she eats and comsumes to strengthen her own soul, the more powerful she gets. She chooses parts of her lovers that she integrates into herself : their memories, their knowledge and their skills...
This way, she collects new bodies, new identities, new memories, and becomes progressively a dire ennemy with a lot of faces, which could be hidden behind every pretty mate you meet...
Even if she looks exactly like the one she duplicates, her comeliness and seduction is far beyond those of the people she imitates...
In her true form she is the most beautiful young woman you ever saw, naked, with a red skin and long, black hair. She has claws on her fingers. Seeing her true form does not generate a terror check.
She can adopt the identity of anyone she knows or imagine, whether male or female, with the very same body (just more beautiful), and with the very same voice. She can also use the voice of someone without having the corresponding body (for the phone calls, or otherwise).
She may seduce anyone in the scenario (but she need to be close to them, and to be in situation to exchange a few words for that). The only one who are immune to her charms are the people who were at the sunday evening mass (when the Angel appeared) who are now under the control of the angel. [that include, unfortunately, some guards from the local prison, and most of the people working in the death row, who will attend the next death penalty execution].
She is a master of Dark Art, if comfronted physically.
The plan of the Succubus is:
Leylah (the Succubus) thinks that the angel will wait for the death penalty of the killer (Jack Crow) to be executed, and after that, the angel will retrieve the corpse, revive him and modify his body to enhance his abilities. So, Leylah sets up their plans accordingly. She plans to sneak into the jail (with the PC) before the death penalty, and there, destroy the soul and body of the killer, thus preventing the killer from getting transformed in an undead killing machine.
But the angel didn't wait for the death penalty as Leylah thought. He is planning to take the killer alive before. As Leylah arrived in town later than the Angel (and she is loosing some more time to make up her plans), it is likely that the PC and her will arrive too late in the jail to dring the soul of Jack Crow and destroy his body. The angel and him will already have broke free.
So probably, while Leylah the Succubbus (and the PC) will be still trying to enter the prison, the angel is already tinkering with Jack Crow the killer, giving him supernatural strength and speed, and some Dark Art power. His appearance is less and less human, but his efficiency as a killer greatly improved.
Leylah and the PC now have to hunt down the serial killer and the angel. Either they are able to catch them before they leave town, or they will have to go in Metropolis for that purpoose [what way the angel is using to go back to M.?]
they now have to intercept the killer and the angel before their return to Metropolis (preferably). (Where is the gate to Metropolis? How the angel plans to use it ?).
