"Hi. I'm Imliss's sister Idaia."

"Oh, hello. Come on in, please." She blinks at Tyelcormo.

"Conner. I'm an Elf."

"...yes, I'd got that."

Why are you introducing yourself by that name?

In case they've heard of Celegorm the infamous mass murderer.

I'm pretty sure Imliss told her the Elves we're friends with are Feanorians.

Oh. In future we should probably keep that bit at least partially under wraps.

Under the circumstances she decided that the potential failure modes were worse if they found out by accident than if she told them herself and also told them some of your side of the story.

Fair enough.

"So we've been trying to figure out the reincarnation thing," she explains to Morwen, "and we think we've found something. It isn't a good something."

"Oh?"

"So it turns out there's a prophesy that Turin's going to kill Morgoth at the end of the world."

"Oh.

A prophecy? How reliable are those?"

"...Normally, very. But this one is super implausible in other respects--he's supposed to kill him by stabbing him with a sword, for one--and humans are supposed to have 'free will, here defined as the ability to not swear binding oaths and run away from prophecy and/or hit it with a big stick if and only if you know it's coming for you.'"

"...so, since he knows he's supposed to do it, he could evade it? But why would he, if he can kill Morgoth...why isn't Morgoth already dead..."

"Morgoth isn't already dead because the other Valar re-imprisoned him instead of killing him. Whether this is because they literally couldn't or because Valar are defective is unknown to me. A good reason for Turin to run away from this prophecy really fast is because it has a lot of really suspicious elements and we can't guarantee that if he tries to stab Morgoth with a sword that won't end with him dead or worse."

"But prophecies are generally reliable? And we don't have a non-prophecied way to kill him?"

"Prophecies are generally reliable but my sister and I are doing everything in our power to pull this one off course because it has elements we really don't like. We have...what we hope will be a way to kill him, if we can get the right resources to the right places at the right time."

"Is pulling off course a prophecy that ends with him dead in favor of plans that might not even a good idea?"

"Dear, do you remember the exact text of the prophecy?"

"No, but, like, the Sun and Moon get destroyed and stuff."

"So that, and also wasn't there something about the world becoming 'perfect' in it?"

"Yeah."

"And that's a problem?"
