I saw several threads like this here, and thought it was a rather good idea, so I'll give it a try too.
I'd run those games myself, but my exams are coming soon, so I won't have the time to master a game. Besides, I have yet to master a game in English.
The themes are not exhaustive, but are only rough indications. Not all of them must be part of the story of course.
1) Book of Shadows (Freeform, BESM ?)
Some books should never be opened, some words never uttered. A few days ago, a group of university student found a dusty old book of occult lore on the shelves of their university's library. This blasphemous tome contained the names and means of invocations of several unholy creatures, succubi and incubi.
Motivated by perverse curiosity, by the taunts of their friends, true belief in the occult or mere boredom, the students read the formulae and called the demons' names.
To the surprise of most of them, the creatures answered.
Since this fateful day, each of this student has been plagued by one of these entities at least.
How will this situation evolve? Will the unfortunate student end as the demonic creatures' slaves? Can they get rid of them? Or even turn the tables on their current tormentors?
( I see both groups, demons and students, as playable)
Themes: Occult, Fantastic, Mind-games, Voyeurism, Non-Consensual, Power-play, Seduction, BDSM, Innocence lost...
2) Harem of the Illuminated (Exalted)
Hidden in the forests of the East, lies the mysterious third Camp of the Cult of the Illuminated. Like the two others this camp's main goal is the training of the Solar Exalted to help them regain their former power...under Sidereal "supervision" of course.
The main difference between this Camps and the other is it's focus on the other type of exalts.
Although the idea of uniting all the different sorts of exalts under a single banner had merits, the roles given to the lesser Exalted are only a mockery of those they held in the First Age.
Young Lunars who can be found before the Silver Pact reach them are taught, sometimes forcibly, to serve the Solars as bodyguards, concubines or pets; Terrestrials find themselves serving as the Lawgivers' squires or handmaidens when they aren't just part of the Solars' harems.
Can this abnormal situation endure forever? As one of the Camp's trainee, will you follow the rules, flee or try to change the situation?
Themes: Dom/Sub, Non-Con, Power-play, Bondage...
3) Dark Spring ( Changeling the Lost, Freeform )
You have only recently escaped Faerie, and are still afraid, lost and disoriented after your durance and subsequent escape. you haven't had the time to take your marks in this world -your world- that has suddenly become so different. you still have to discover what is left of your mortal existence. Perhaps are you considered to be dead, perhaps a fetch, creature of shadow and illusion live has lived your live since your abduction.
Fortunately for you, you have been found by others like you, Changelings as they call themselves, people who know how you feel, who suffered through the same ordeals. They brought you to their freehold to mentor you, teach you what you had to know to survive in this world of madness and magic.
Can you trust your knew companions? Will you try to reclaim your old life? Your destiny is in your hands.
Themes: Madness, Loss, Fear, Romance...
