...the thing all good Gothic Horror films and novels are chock full of: SEX!
Well sensuality, mostly. I find it kind of a 'softball' move to go to the 'child ghost' and 'child sacrifice' shtick to create peril and mood but - as far as my reading indicates - completely gloss over the inherent sensuality of the Gothic Horror tale. Am I missing something? I'm not asking for Keanu Reeves getting seduced by a coven of Vampresses... Vampressi (I dunno), or other over the top excesses from modern movies attempts at the genre. Rather I'd like the subtle under currents of tittlating sensuality you get in Bram Stoker's original novel, or - if you've read it - Carmilla.
What about the implicate sexual struggle found in Frankenstein? The disturbingly erotic tone of Wuthering Heights?
To be honest, it's probably just as well that this is left out of the adventure as published. What those Gothic Horror films and novels is not good, wholesome, fun sex, but rather various depictions of sex gone horribly wrong: the rape metaphor in "Dracula", Heathcliff's unhealthy obsession in "Wuthering Heights", rape, incest and pedophilia in "The Werewofl of Paris", and so on.
And while there's certainly a place for any of these in storytelling, and even in RPGs, that place is probably not in a product aimed at the mass-market. Indeed, it's probably best just to leave these themes out almost entirely, and let groups add them as much as they want.
Anyone have any suggestions to add a some sexual dynamism to the adventure?
Firstly, speak to your players to find out both how far they're willing to go in general and also if there are any specific areas they want to avoid. (A group might be happy with a solid R rating in general, but insist that rape in particular be avoided, for instance.) And make sure you respect the
least permissive of these - this isn't an area for insisting on a compromise or for pushing something on an unwilling player. (If you play in a public area, you'll also need to be mindful of your potential audience.)
Beyond that, it's mostly about details and descriptions, and also about including (and emphasising) various characters motives for doing things. So when a vampire drinks blood, play up the sexual rush that is implied. When a lycanthrope changes, emphasise that they're casting off the restrictions of their civilised human nature and freeing their more animal urges. Emphasise Strahd's lust for Ireena, or his carnal attraction to his chosen successor (and the thwarted lust when it inevitably turns out the successor just doesn't measure up).
