Black court vamps are actually quite powerful, and you may not want to use one of them right away, especially if everyone is learning the system.
How's this for an intro:
Someone has been killing the local cats.
Who?
The local little folk.
Why?
In retaliation for a cat killing
them.
What?
A local minor talent (who can turn into a cat) has declared war on the local little folk.
Really? Why?
Because one of the little folk though it would be funny if the shapeshifters mom's heart medication was replaced with Folgers crystals, or something, and the shapeshifter blames
all the local little folk for this.
Wow, what are we going to do about it?
So notice that you have plenty of things to fight with, should you be interested in fighting, but none of them really have the ability to grab you and rip your spine right out that BC vampires do. And if you want to throw in some bigger fights, you can pull out some fae (ogres, gruffs, whatever) which you can justify as having (whatever) combination of abilities.
For example, if the party if trying to find the little guy originally responsible for switching the medication and put his head on a kebab stick, the fae can be owed some favors by some bigger fae...
And if the PCs are having trouble taking the little folk seriously as an enemy, have them find, I dunno, half an earth worm or something in their food, that one of the little folk put there. Point out that the little folk are everywhere, and almost unseen. If would be horrible if one of them slipped some
Candiru into your bathtub one day, wouldn't it?
