Eletheria Escalanas of the Escalanas Ranelle, Vampires and the Origin of HMHVV Options

[Euiscerati]

In Earthdawn companion under the Key Knowledge section of Thread Magic, a 'vampire' is used as an example of gaining key knowledge of a true pattern. What's strange is that they just throw out a vampire even though vampires don't appear anywhere in the Earthdawn books. Not in Creatures or Denizens or Horrors even. Yet Vampires are acknowledged as being part of the game world. The only mention of what could be HMHVV appears in Blood Wood. Under the Escalanas Ranelle description is described Eletheria Escalanas. She was a powerful magician who was accused of dealing with dark forces, etc. So right before the ritual of Thorns she is kicked out of the Wood. After the scourge, people, especially Blood Wardens start to get killed. Their hearts are ripped out and all the blood drained from their bodies on nights of the full moon. A pale, ghost-like woman fitting the description of Eletheria seems to be the one doing it. Eletheria seems to have surviveed the scourge, but is she the first (wereX?/)vampire in 'the world?' The Queen of the Damned, so to speek? The whole ripping out of the heart and drinking blood seems like a not-so-subtle hint.

In Barsaive in Chaos 'vampires' are listed as horror constructs but that doesn't sound much like HMHVV which is a disease of the blood. I don't know if they are supposed to be 'Vampires' or are just 'vampires.' HMHVV is clearly blood magic, literally, not something directly tied to Horrors. Seems like Eletheria was dabbling in serious blood magic searching for a way to survive the scourge and created a way to survive the scourge by sucking blood, but who's blood did she suck outside during the scourge? Horrors? Maybe she struck some deal with a Horror.

So does that mean Vampires and those who suffer from HMHVV are Horrors or Horror Marked in some way? Or does it give them some unique power to resist Horrors as Eletheria seems to have done? I guess in Shadowrun terminology, Eletheria would be a Banshee.
