She nods, and she pops off to where he expected her to be able to find Rúmil.

Pretty, symmetrical, austere. 

It's almost vaguely institutional, all "we hired a really slick architect who forgets people have to live here" -

She can't detect a Rúmil-mind around. She will ask the nearest person for directions.

The nearest person confirms that's his house and he should be in.

...there is someone in there, but -

She knocks.

The person also looks like Rúmil. "Hello?"

what happened to you

"...hello. Is this a good time?"

"...I'm afraid we haven't met. Rúmil."

"I'm Bella."

"How can I help you?"

"I used to live in another Valinor, and I know another Rúmil," who looks the same and has the same name but bears only species-level mental resemblance what happened to you "and I was curious."

"About what?"

"About you. But if this is a bad time I can go."

"Are you here by the King's leave -"

"Which King?"

"...the King of the empire?"

"I'm new to the politics of this Arda but I did think it had several kings and wanted to check - uh, Maitimo told me where to find you, if he's the king you mean."

"Come on in."

She goes in.

It's a pretty house. "Can I get you anything to eat? Drink?"

"No thank you."

"Welcome to this Arda. I think the jumpers call it 'Evil Arda'."

"They do. I'm considering asking them to stop that but I'll have better luck if I can supply a replacement name." Pause. "I have powers that let me recognize people by the way their mind looks and - and for some reason you don't register like your alts. Maitimo does, it's not just being from here."

"Were they prisoners of the Enemy?"

"Yes."
