Nothing is ruined, not exactly. People are just resistant to someone taking an idea and shoving it into a setting where it isn't explicitly supported. This is exacerbated when you have something like the OP, which makes a bunch of concessions to the lore to justify a thing that doesn't already exist, and could really be done in any number of other games or settings.
People will want to roleplay things they like, but two great tastes don't always taste great together.
Closer to the topic: As others mentioned, Voidsent are the closest thing we'll get to vampires unless SE comes right out and does more with them. We know they're drawn to corpses and it isn't unreasonable at all to have a voidtouched person crave blood. Just don't give them a list of superpowers with the offset "weakness" of things that already kill everyone else. Don't confuse vulnerability with a weakness: Conventional vampires were only able to be killed by stake, decapitation or fire. They literally didn't die to anything else. They were unkillable unless you did these things to them.
I didn't think this needed to be explicitly stated, but don't play unkillable things in RP.
