This Comic's Cast:

I'm fudging things just a little. Technically, if Blacula was in the castle then Maria could have run across him. Obviously Thereshiri would know who he was, since she lived in the castle for centuries. But Maria would have had to have seen Blacula when she was in the castle the few times she was there.

Now, the reason it's a fudge is because Blacula was in the Cursed Prions, and if that area existed, then it had to be in continuity, and if it was in continuity, then Maria's quest through Symphony would have lead her there. Now, maybe she didn't see him, or maybe her quest isn't in continuity (I'm hazy on that fact in the comic). But yeah... I'm playing a little fast and loose with the details here.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
