Alicornutopia

I certainly wouldn’t want to touch it until I knew who it would attach me to, and probably not until I was already in love with them, and even then I’d probably need an additional factor like inadvertently hurting them or somebody coming at me with mind magic. I suppose the “coming at me with mind magic” might be enough to get me to touch it anyway, depending on the magic in question and the likelihood of it affecting me.

Being in love and knowing I would necklace to the person I was in love with, combined with knowing how the necklace works all ends up to 'I am okay with touching it after I am in love with the person I would necklace to.'

I'm much less calm and reserved about touching the necklace and then not knowing who'd I get. I would be functional, but any time I thought about it I would have to fight down some directionless panic and mild despair.

My reservations come mostly from ill understood nature of the necklace.

They have a sample size of two couples and those haven't been studied for long.
What if the effect changes over time? What if it has interactions with some magic somewhere? What if it is powered by the souls of the unborn? What is the effect of feeling that kind of love over millenia? What happens to an Adarin with broken number system over time?
Objective truth examination helps some, but only interactions in Chamomile can be studied that way.

It's not actually an urgent problem. Immortality has been cracked.
Take a hundred years to think it over, go to therapy, enjoy your no longer totally isolated life. Spend time with Aya, maybe you are not as incapable of normal love as you think.
Then think about un-reversible alterations to your psyche. You will live with those for a really long time.

Maybe write a love spell yourself or have Isabella write you one instead of trusting an artifact of unknown origin.

I really love Primes independent nature and how he does Adarin stuff on his own terms.
Him going with the first plausible solution and throwing himself to the mercy of an alien artifact when he has the resources of the Multiverse at his fingertips really sits ill with me.

you know, I agree with Modrony's logic, but I can't heklp but feel that Prime would necklace himself anyway. Also, I want to give Prime a hug.

Astrid and Martin relationship would be changed/strained by the fact they are sort of the same person?

The necklace permits polyamory? or that is a Zev-on-Zev trait?

Astrid and Martin would weather the revelation that they are alts pretty well.

The necklace doesn't enforce physical monogamy. It does kind of effectively do emotional monogamy, but Zevs are good on non-emotional sex.

Are Astrid and Martin the first known case of alts naturally occurring concurrently in the same world?

No, Aianon and Ansharil were that too.

Ahh, I'd been thinking of Aianon-and-Ansharil as collectively a single instance of the Joker template.

So, what was up with mysterious-person-who-looked-like-Renée, if there was anything up with them other than being a source for Phix to get an amulet.

That's based on an event in the canonical Skin Deep comic. Ghosts!
