Is it indeed where they want to go?

So far seems like it.

There's a fairly thoroughly picked over room, with a long dead fire and an old satchel set up in the middle.

Past that is another door, leading to a room that's almost entirely taken up by what seems to be an enormous sphere, leaving only a narrow walkway around it - and now faintly they can hear voices above them.

"I'm telling you, we tried that combination. I don't want to keep just random guessing, we don't know if it'll set off a trap or lock us out."

"Hrngh. There's no clues, though, usually the dwemer left behind something hinting at it. I don't know we have another path than going through every combination."

She looks at Ena.

Who has her head tilted back and her eyes closed, and appears to be counting down from a very large number. She does sigh soundlessly, then glance over at Elana, shrug, and nod her head towards the ramp up.

Up the ramp it is.

"Lianda!" Ena calls out when they reach the top, dropping all pretense of stealth. "Fancy seeing you here. How're the munchkins?"

Lianda turns and crosses her arms - she doesn't seem particularly surprised. "They're fine, though Runa's heartbroken you haven't been around. What're you doing here? What could you lot possibly want with another Elder Scroll?"

"Oh, you know, search for eternal knowledge, the secrets of the universe. What do you want it for? The Dawnguard?"

A pause, then - "I need it to project myself back in time to the Mythic Era so I can figure out how to kill Alduin, who is probably either Akatosh or his son."

Ena blinks. Then blinks again. Then - "I leave you alone for one month! One month! And you're trying to pick fights with the Divines?"

"Just one Divine, and only maybe."

"What makes you think going back in time will provide an answer?"

"Alduin's been cast out of the world before - not entirely defeated, but delayed. He's early again, and I think he's weaker while he's out of his proper time. I just need to find out how the ancients defeated him."

"Sword and spear and strength of arm?"

"...Not likely. For a variety of reasons. And you still haven't said what you're doing here."

"The Elder Scroll. The same as you."

"There isn't exactly much else here. What do the vampires want with an Elder Scroll?"

"You speak of 'the vampires' as though we are a single monolithic entity, unified in purpose. I desire the scroll for my own reasons, knowledge chief among them."

"They're not exactly safe, you know. I'll be able to read it, and can tell you what it contains, but you already have one - and I'm no convinced you should have this one once I'm done with it."

"Happily, I only require its contents and not the Scroll itself. And this place is, reportedly, a means of transcribing that contents."

"...What will you do with your newfound knowledge?"

"Save the world, in my own small way."

"From what."
