"Yeah. I suppose I could try scavenging from what's left of his little cult."
"I'm not quite clear on what you need. People, obviously, but not which part. Brains? Bone? Blood? Souls? Force energy? Does it kill whoever you take it from?"
"Blood. Judging from the number of bite marks on some of those people, it's not necessarily fatal."
Revan eyes said bite marks. "If scavenging doesn't work, I can feed you. Maybe not comfortably right now, I was just stabbed, but I can heal. It'll be fine."
"I," he says lightly, "am going to pillage while you scavenge. Let me know if scavenging doesn't work."
Off he goes to drink the blood of dismembered cultists!
This involves his teeth lengthening into fangs, which is reasonable, and his eyes turning yellow and his forehead acquiring a hard ridged scowl, which seems unnecessary.
Off he goes to pillage for information on how their summoning thing works. And just for general stuff and information.
Also, neither the throne room nor the bedroom has any windows. The bedroom does have electric lighting controlled by a simple mechanical switch in the wall.
The lack of windows is explained when the other exit from the throne room leads to a stairwell that takes him up to the aboveground portion of this bizarre quasi-castle. There's a dormitory there that seems to have housed the cultists, and more simple electric lighting. Very low-tech, this place. All the doors operate mechanically, no automatic opening, no powered movement, just hinges and a handle. There are a few windows on the ground level; outside, it's a clear night, with one large and quite beautiful moon in the sky amid a totally unrecognizable configuration of stars.
Meanwhile, Mark is discovering that dismembered cultist blood seems to pass muster with his new vampire appetite. He experiments with deploying and retracting the fangs-and-forehead-ridges ensemble. It seems to be very definitely a package deal, more's the pity.
(He only giggles a little when playing with the door.)
Revan takes some time to sort fiction from nonfiction. It's - uh, a challenge. Especially when one doesn't actually know the history of the planet. He copes, anyway, and digs up what seems to be a history book on something called the 'American Civil War.' He verifies that it's nonfiction by skimming it; it's too dry and technical for fiction, and there are various citations in the back. He's almost entirely sure that it's nonfiction.
He's going to get Mark to check it anyway. It's not like Revan's familiar with Earth history. He heads back down to the summoning location, book in tow.
"I haven't found any information on, er, this. Or vampires. And most of the books I've found seem to be fiction." He hefts his discovered book. "This was about the only book I could reliably identify as nonfiction."
He only has to glance at the title. "Yeah, pre-Jump Earth, all right. I recognize the historical event in question. Let's have a look at the publication year." He opens the book. "1998. Which puts us somewhere between 2010 and 2030, I'd say, judging by the quality and condition of the paper. Paper books show their age pretty reliably, some of them. If this Earth's future is congruent with my past, interstellar travel will not be invented for another couple of centuries."
He visibly brightens upon Mark's analysis. He correctly found a book that was nonfiction, and correctly guessed that Mark could figure out more from it than he could. It's the little victories, really.
"Well, by rights of conquest the too-tactically-pathetic-to-accurately-
He pokes his head into the bedroom, then comes out looking thoughtful.
"Is it just me, or does the lack of windows really not fit with this man's image?"
"It's not just you," agrees Revan. "The entire place is built for - well, to look innocuous on the outside, and then for his minions to treat him like a god on the inside. It isn't very practical, but it's not impractical in the way I would normally expect. Where's the opulent room at the top of the tower that overlooks everything? The dramatic balcony and the stained glass windows? He didn't seem to me like a man that lacked the ordinary tasteless style from these sorts of people. You saw the fur robe. He had a sense of the theatrics. I wonder why the design choice. I feel like I'm missing something..."
"Vampire-related reasons would be my first guess, which makes me reluctant to go upstairs. But I don't intend to stay in the murder cult's windowless basement for the rest of my immortal unlife... Some legends have it that vampires react badly to sunlight; that might be it."
"Possibly. It's night. If it's sunlight you should be all right, unless reflected moonlight counts enough."
Up the stairs he goes!
He does not explode in the moonlight.
"I am glad I didn't explode. So, moonlight's safe. Sunlight is still an unknown."
"Yeah. And we should find a spot for you to stay in case sunlight turns out to be deadly. Mm. Here's better than nothing but it still screams 'This will end badly' to me."
