Let's go.

Ena shows her where the tomb on one end of the hall has a button, that causes it to recede into the wall, revealing steps down to a door. "Figured it out because I've seen something similar before. Plus the button doesn't fit well in its setting."

The cavern beyond the door is fairly poorly lit, consisting of islands connected by rope bridges, and contains what Ena described, plus two coffins, a throne, and a shrine to Molag Bal in one dark corner, and in another a statue of Hircine and some werewolf totems. There's a few weapons on display, too, and some miscellaneous other things - mostly jeweled items, a few of which Ena's able to identify as "Originally stolen a long while ago, the proper - and legal - thing for the museum would've been to return them to their owners."

Elana grimaces at Molag Bal's shrine.

"What if the owners are dead?"

"...Not entirely sure. I know the polite thing to do is return items to their heirs, not sure about the legal thing."

"Does knowing the legal thing often come in handy for you?"

Shrug. "Sometimes. Used to more often, back in Hammerfell." 

"You're a long way from home, then."

"Yeah. Skyrim is - very itself."

"Why travel all this way?"

"This is where my sister was - I think she came to Skyrim on her father's trail, he was a Nord - and Hammerfell was becoming... Not a place to stay, what with the Thalmor. Skyrim's at least a lot less friendly to the elves."

"I seem to have slept through the eras of a human-dominated Tamriel."

"I know some history, I can try to explain things if you'd like."

"I've skimmed the books available upstairs already."

"Find anything good?"

"In historical value or monetary?"

"More meant interesting to read."

"One that claimed recent events fit the signs of a world-ending prophecy."

Snort. "I've heard some people declaring that the dragons are the end of the world, but - that's just so ridiculous to me. We survived the Dragon Break and the Oblivion Crisis, a bunch of overgrown fire lizards that're mostly just in Skyrim are hardly going to threaten everything."

"People like to think they live at the end of days. It makes them feel important."

"Were end of the world prophecies a thing in your time, too?"

"For my family, they were."

"As in there was one involving your family, or your family believed in one - "

"Both."

"I hope there isn't a world-ending prophecy involving my family."

"It's not as much fun as it sounds like."
