Fae make promises and create beauty, and when betrayed they gain terrible power. Keep a fae happy, keep yourself safe. Keeping a fae happy naturally includes handing them your power, so the relationship gets more and more imbalanced until you're willing you escape it, no matter the consequences.
Ghosts channel their past traumas into deadly weapons. Their existence depends on them constantly having unfinished business. When they are their Darkest Selves, they are invisible. They have a messy co-dependency with their past.
Mortals have only one card, and it's the victim card. Fortunately, they know how to play it in a million ways. Being a Mortal is all about meeting your needs through sacrifice - letting others have their way with you, and leveraging that in order to get what you want.
Werewolves are all about walking as close to the fire as possible, trying not to get burned. Werewolves have hungers, which are physical things they want, bad. They get a bonus to trying to seize them. At their Darkest Selves, they must attempt to kill or maim everything that stands in the way of their hungers.
Infernals are all about walking as close to the fire as possible, too. Except, they aren't playing with rage, they're playing with debt. Infernals can go into debt in a bad way, debts owed to the devil, or the stars, or the demon living inside their heads. Whatever. At their Darkest Selves, they aren't themselves. They're someone else, coming to demand repayment.
Ghouls are beyond the realm of the living. Unlike the Ghost, there is no unfinished business. They are the living dead - gaunt, pallid, beautiful in their distance. Ghouls are good at heartless manipulation, severing ties, and they possess some cool beyond-the-grave powers.
Vampires are all about manipulation, seduction and insincerity. Their two strongest stats are Hot and Cold, and they are well served by jumping back and forth between them. Unlike Ghouls, Vampires have no motivation to sever ties, even when those ties are temporarily working against them.
Witches are all about wielding dark magick, manipulating from afar, and interfering with other relationships. If you like the idea of pitting your friends against each other, putting nightmares into peoples' heads, and wyrd magick, then you're probably a witch waiting to happen.
