Annie doesn't either. Rirosseth probably knows what she's doing. If anyone wants to know why she is so concerned about talking to Rirosseth she's got a great excuse: Rirosseth died trying to protect her.

Oh? They'd heard Rirosseth was attacking people.

Rirosseth didn't hurt them, she was trying to get them to stop singing because it was hurting Annie because Aulë hadn't yet provided the insulation magic.

Well, but when you've murdered enough people you lose the benefit of the doubt on whether when you're attacking someone you mean to hurt them.

Annie isn't particularly interested in quibbling over that but it is a fact that Rirosseth died trying to protect her.

And that's to her credit, sort of.

...Annie is much too fucking devoted to the fucking bliss of Valinor to press the point on 'sort of'.

And the Valian Years blissfully roll by, and there are yet more orcs, and news trickles in very slowly from across the sea. 

And one day Celebrendes rushes into her rooms in Khazad-Dûm and says "we've got it."

She feels like she's able to breathe for the first time in a long time. "Oh, good," she says, "okay, who doesn't mind a one-way to Valinor and is on good enough terms with the Valar they won't be arrested on the beach -"

"Eliel might know someone -"

"I'll ride out to ask her right away." She does. Eliel knows a woman who lost her husband recently and has been thinking about emigrating and would be happy to deliver a parcel to Istarno. Lírnith carefully stays out of this; rumors of her involvement would only slow things down. The envoy gets one of Círdan's great grey ships and she sails west to a continent no longer barricaded by its gods.

And she disembarks in Alqualondë and races for Tirion and knocks a few days later on Istarno's door.

He answers. "Yes?"

"We got human immortality." She presses the necklace into his hands.

He lets it slide through them.

"Is she somewhere else?"

"Eru, I hope so."

"..."

"You're Years too late."

"I'm - sorry?"

"Me too."

(The messages stop coming and she is not quite too broken to do inferences and she knows and she lets the despair swallow her whole and Mandos decides eventually that she is ready to be reembodied and is distressed at how little there is left to stick into a living form.)
