Vervain hurts/weakens vampires.
Vamp strength depends on which generation of vamps they received it from; the farther the source is from the original, the weaker they are, though the difference is negligible between closer generations.
Doppelgangers appear sporadically down the bloodline, but always appear when their line is near its end.
Doppelgangers are a very rare supernatural people or, better still, supernatural events. They draw other supernatural beings to them, turn them into their loyal puppets, make them love them, protect them. Of course, it's not all good for the doppelganger; their blood becomes highly sought after for magical purposes, and that can twist the love of others into something sinister.
New Doppelganger power supersedes old. Vamp's doppelganger ability is diluted.
Siphon witches – are abominations, magically created witches that were made wrong and need magic to survive. Kai survives because he's in a magically rich community; he won't last outside of it. His father, desperate for an heir, created him, but learned of his mistake too late. The sister was a happy surprise. They merge magics into one, not people into each other???
WEREWOLVES – are from a failed curse; the venom was originally meant to create more, but failed, and now it's passed through birth.
OR werewolves were created to hunt vampires; other witches answer to the vampire problem, to try and wipe them out.
Reason Homes need invitations – it's because a natural magical barrier is formed, keeping out other harmful magic when someone dwells in a place long enough and gives the care it deserves, so those who don't receive this safety net.
