"Valinor would likely have been evaluated as secure by its occupants."

'I could likely specify contingency locations?'

"If they became widely known to be such they could be targets."

'Was this the cause of your doubt,' Ancora asks Alassëo.

He nods.

'I see.'  Acting stance.  ''It is also my understanding that some people may eventually come to desire that they have no extant instances.  Though this is not an urge I myself can comprehend in more than the abstract.''

"Some people do come to desire that. I... don't think that instances that Melkor had for a while should get to decide that they shouldn't be forked from earlier, but some people come to that conclusion more... clearheaded."

'It seems a poor system if those desires could not be accomodated.'

"Yeah. The clearheaded ones, anyway."

'I should delegate determining which category people fall into.  I do not expect I would have an aptitude for it.'

"Seems a reasonable guess."

'Do you have any proposals for other methods of copy protection with fewer vulnerabilities.'

"Uh, not off the top of my head. Something something encryption - do you know about encryption -"

'It is like deception in that it makes something more confusing on purpose, but unlike deception in that it clearly and honestly denies someone information, and is backed by one's power instead of the redirection of attention away from the content one wishes to remain hidden?'

"...I guess you could put it that way. Are you aware of any specific examples?"

'I have encountered mentions of chiplocked content.'

"Yeah, that's a sort of advanced concept though and I don't think it'll work well for this in particular - it encodes things with the way a particular brain works, which is why chiplocked content can't be accessed even by demons conjuring for it, but that relies very much on a physical brain taking particular mental actions."

'What do you see working well for this in particular.'

"There's a thing you can do where you can encrypt things in such a way that you can store them in multiple locations and need at least three of the backups to make a complete decryptable one."

'I am capable of teleporting to random and random-within-given-parameters worlds in addition to ones I have already visited or am aware of.  Scarcity of locations would not limit this.'

"Ah. Well, scratch that idea then..."

'Oh?'

"- maybe I misunderstood you? If a bad actor had your power they could find all the locations."

'I expect none of my conspecifics to take an interest.  Perhaps nothing stable should be built upon that expectation, but are you aware of a way for other types of being to achieve the same result?  I had meant that we could spread locations across as many universes as seemed desirable.'

"That does help, interdimensional travel abilities are probably rarer than intradimensional ones though I should maybe check that assumption with Bar."
