Raezenoth? Is bored. He has run out of things to do, and Idania is busy. With her boyfriend. Again. He would damn him, if he did not make her so happy.
He decides to go through a portal an explore. It's not without forethought, he's not stupid, he avoids the witch's world with its 'soul-pets' and the worlds where he could potentially be under threat, or expected to hide. That leaves, quite neatly, exactly one. Medallion and the daeva's set of worlds are dangerous and flying in public is considered abnormal. Spellbinders take time to charge their spells, and so he has time to react to them. The same is not true of Prime's world, though that's his second option. The world with spellbinders is his first.
That is why Katydid and Rain get a divine visitor.
"Hello," he says, as if his behavior is utterly normal.
"Picking one person from all others, with full disclosure of their flaws and quirks and finding you love them anyway, to be your partner and confidant. Sticking by them through - whatever happens after, whether it be the apocalypse or war or famine or - something that could potentially be distressing and drive you apart. And trusting them. Absolutely."
He kisses her forehead. "I'm going to guess that it is slightly less of a - thing for you."
"Considerably less, yes. I mean, it's serious - but it is a thing you do when you are serious rather than a serious thing intrinsically."
"I mean, they are probably on the same order of magnitude of seriousness, so it may be academic."
"Yeah. They seemed pretty happy to spend the rest of eternity together. While flaunting."
"Mmm. Tempting, but I don't think the danger's worth the ability to cuddle souls and talk to myself. Besides, we can't lose our nerve now. We got this far without the cheaty soul birds."
