"Lianda's not going to be an effective interrogator. Especially not for a vampire. Threats aren't worth much, and she's not good at believable bribes."

He frowns.  "...Not a lot in the way of interrogation magic, is there."

"Not at all."

He glances between them, then addresses Ena: "Think you'd be an effective interrogator?"

"I have some experience."

"I don't know what bribe you'd even give to a vampire, other than blood... but we may be getting ahead of ourselves anyway."

She nods. "A large part will depend on who we can get, if anyone."

"Yeah.  Let's move ahead with stage one for now."

She nods. "I'll head out, then?"

"Good luck."

"Thanks. Hopefully I won't need it."

She does not, in fact, need a lot of luck to come back alive from her stakeout, but only because she doesn't turn up anything interesting.  For the eight-odd hours she keeps watch, at least, the place is as quiet as, indeed, a tomb.

Unfortunately not actually all that surprising.

She makes a list of entrances she can see, sketches out elevation maps, walks around and identifies exterior defenses. This entrance is the really obvious grand one. This entrance is hidden in a shadow of something else, but she thinks that arrow slit has sight onto the approach to it; if they're smart they have someone watching from there. This entrance over here leads to a rubble field and seems disused but also the rock above it looks dubious. That other side entrance has grass worn down away from it and the mud looks churned. Those two entrances are on balconies overlooking the external courtyard, and are probably for feeding archers into these defensive positions in the event of an invasion. Probably they have guards.

She heads back to the team to report her findings and suggest they spend more nights watching.

"Yeeaaaah, in retrospect that may've been a bit of a longshot.  But if we're not on a super strict deadline I bet more stakeouts'll eventually turn up something."

"And it'll give me time to make maps of possible internal layouts given external conditions - the ancient Nords could only get so fancy with their bracing. There's limits to where you can put tunnels and rooms without the roof falling on you."

"Oh, that's clever."

"It's a lot of guesswork, so I won't be able to get an exact map, but, yeah, there's some layouts they can't have. And while every tomb's different in its particulars, there're a couple of popular broad styles."

He nods.

"Is the information I got enough for that?"

"Should be."

"Then I'll spend today resting and head out again once it's close to twilight."
