She has the concept from what exists of descriptions of the empires their ancestors fled (and stories and simulations, but those are more likely to be inaccurate to a reality). She considers.

While some might obviously think better of someone who had not taken such a job, if one's world has the dynamics that lead to such jobs existing, it does seem likely that someone will occupy them. And those are not likely to be the people at the level of power of driving those dynamics.

If she was currently in the other world attempting some intervention, the best course of action might in some cases involve making this interaction hostile; at the moment this does not seem likely to be the case.

She nods.

"That is not considered a job? Or just not one that would tie you down? Is it one one retires from - I notice you said 'was'."

"Doesn't tie me down, yeah. Flexible hours and all that. Got hard to keep going when my clients couldn't remember I existed long enough to pay me."

Nod.

"How long ago was that, if I might ask?"

"A few decades. I'm not so good at exact times, though." She doesn't look old enough - for a normal human - to have been an assassin a few decades ago.

"How long do people in your world live?"

"If something doesn't get them first, usually seven to nine decades. Some people get to ten, though."

That sounds fairly close to what hers had before the work that has so far been successful on it.

"How old are you yourself?"

"Hard to say."

"Oh? Would it be outside the usual range?"

"Yup - you can also make the world forget concepts, like an individual's death or age."

...that is a new dimension in what she knows of this power's capabilities, and a significant one.

"My. Is that particularly costly? Is there a reason it is not commonly done?"

"It's costly and most people don't know how."

"Costly in the sense you earlier mentioned, or are there additional costs?

For what reasons is the knowledge not more widely spread?"

"In the sense I mentioned earlier, and it makes using the magic at all later risky. And most magical knowledge isn't widely spread, and if you get forgotten about it's harder for your innovations to get spread, too."

Ah, that last would be an interesting effect of their system.

"Risky?"

"Your death ends up dwelling in the Forgotten World. Which you have to go into, in order to move things between realms."

"What does that entail? Does it become a physical entity? Does it attempt pursuit?"

"It isn't really physical, but it does need to search for and find you. Haven't gotten caught by mine, yet."

She's still generally interested to know further what the Forgotten World is like, and if it resembles a more regular world or is entirely different.

"Quite extremely different. It's - fragmented, kind of dream-like."

"Oh?" (Dreams are a subject of some amount of interest in her world; various people study them.)

"The things shoved over usually have some amount of land around them, but it's - hard to focus on, wavery, and easy to forget the exact shape of. But forgotten things aren't all coherent, or capable of existing together, so - it's kind of like they're on islands with paths between them, but some of those paths are just thoughts."

"Is it possible to live there in a longer term? Or does the deletion of a person generally kill them?"

"Some people do live there, yeah."

"Some?"
