Yeah, that’s what I was thinking of when I said “stronger non-taieli magic”

And can you articulate how the monument would not be destroyed by putting in twice (or ten times, or something, if there is some inefficiency) as much epru as the monument creators put in beshenn?

...I mean, the answer is more or less "it doesn't work that way"?

Beshenn can make things conceptually impossible to destroy. Epru can destroy things, but not when it's conceptually impossible to do so. Epru can't permanently destroy a daeva or a Downsider, either.

But I expect then epru must be able to erase something that's not conceptually impossible to erase so completely it never existed in the first place?

...huh?

What is it that you expect about epru, and what led you to expect it?

I expect that if you apply enough epru to a given thing, you can erase it so completely it's like it never existed in the first place. I expect this because if it can be made conceptually impossible to destroy a thing, it seems like it can be made conceptually impossible for a thing to have ever come to be.

Oh. No. That would be too much like time fuckery, which is pretty firmly in the "if you try this your desired effect will be eclipsed by extraneous nonsense" region of naharr.

Tune fuckery still could get rid of it I expect, though?

The asymmetry in the magic system seems weird still, but at least I understand what’s going on there.

How do they ensure no other magic transfer method supplants this one? How were those previously invented?

Time fuckery could get rid of what?

The previous magic transfer methods were all invented using whatever an individual person's best guess was about how magic transfer should work.

Ensuring that no other magic transfer method supplants this one is accomplished by using beshenn to make it impossible for this to stop being the only valid magic transfer method.

The monument

Wait, how did it become the only one? Weren’t there others which were somewhat effective even if most were weak or completely depleted?

I'm going to rule that you would have difficulty using time travel to get rid of the taieli monument because its home universe gets snippy about that sort of thing in general.

They made sure to have the monument take up all of the ability-to-distribute-taieli so there wouldn't be any more of it loose to cause trouble.
