"It's not very hospitable. People don't die immediately, especially if they know how foraging works, but - there's not much food or water."

"Do they themselves retain their previous memories?"

"Generally, yes."

"Is it possible to have children there?"

"Haven't heard of that happening."

"Does it cause miscarriage in those already pregnant, then?"

"Not actually sure on that."

Nod.

She checks her tablet again.

"...Did the invention of computer technology make deletion more difficult due to the greater records, or is that simple to take care of?"

"Records get rewritten too, just the same - you're changing history. It's harder with higher populations and more inter-connectivity, though, because you have to keep track of more that could change."

"I was more referring to how much of the detail work of the records changes you need to keep in your own mind."

"Ah, far as I know none - they change on their own once you change the base event."

"Interesting. Are there other aspects of changes that is the case for?"

"There's a lot of detail work that gets filled in. Specific conversations, memories, any small changes."

"Interesting. And what doesn't get filled in and one has to handle one's self is -?"

"The main important thing is what you, personally, would remember to be different - though it's recommended you learn as much as possible about what could change so you have more control over the result."

"Oh?"

Shrug. "Most people don't want to make basically random changes to the world, and the more you leave up to the magic the harder it is to pull off, anyways. Also if all you've done is read a history book and you're trying to change that, the magic's more likely to make the historians wrong or the book contain typos than to change the original event."

"Ah, I see." That answers her question with respect to control as well. "Are there other such patterns in what the magic tends to do if left somewhat to its own devices, so to speak?"

"Not that I've noticed."

She imagines the nature of deletion might make it difficult to put together anything like comprehensive data on instances of its use and how they took place, would that be correct? 

"Exactly, yeah."

...If you got to the Forgotten World and return, do objects you are carrying at the time travel there and back with you?

"Yeah, though I'm not sure they - or you - get Forgotten while you're over. Though it'd be hard to test that, since the world would revert when you came back even if it did change."

Ah, interesting. She wonders if forgetting extends to other worlds, like this one or her own. If it doesn't, that would have some potential. 

While one is in the Forgotten World, is it possible to note what else is there and then keep that knowledge when returned?

"You can, but there's not usually much near where you cross over."
