I'm curious how one might go arranging for an item or object to become permanently lost, and completely inaccessible to everyone (I would prefer a method that's reasonably secure against even divine intervention, but certainly understand if that's asking too much). This would include the person who stores the item in this fashion, as well as anyone who not only knew the exact method employed, but perhaps even watched it happen. Note: I want the item to remain completely intact, wherever it ends up.
Here are a few ideas I had, but they suffer from some problems that make them less suitable than would be desirable.
- Put the item in a Secret Chest and then destroy the miniature. It sounds like it would, however, be possible to mount an expedition to the ethereal plane to retrieve the item. Is there something you could do to a secret chest to make it impossible to retrieve, or perhaps open or remove from, the ethereal plane? Or is this a dead end?
- Create a demiplane, put the item there, and then give it the dead magic trait, after which you kill yourself. This sounds like a fairly good idea, but do you need to cast permanency after the dead magic trait is added for it to remain past the casting time? It seems like the answer must be no, but some clarification would be nice. If there's no portal and the plane has dead magic, there's nobody who can get there, correct? (By the way: what happens when you die in an area of dead magic?) Alternately, could you add a portal, place the item on the dead-magic plane, exit the plane, and then somehow destroy the portal?
If what I'm asking for sounds too far-fetched, I'd be willing to settle for the following: only abjectly evil beings, including undead, could realistically hope to acquire the item. I mean this in the sense that the alignment must already be evil, not in the sense that doing this would cause your alignment to immediately become evil.
It seems like there must be some interesting trick that could be pulled off, like a magical catch-22, to make an item irretrievable. I'm just not having an easy time coming up with one.
