There is a lot of time spent making portals to various places. Pantheon starts as the unofficial hub, and then essentially becomes the official one. Prime makes a portal to Iobel's and Edarial's world, and then he gets to checking out the various new planes he has access to. One, in particular. It's really rather minor, in comparison to the others, but he considers it important.
Few people have the chance to - go back, do something again. But the other version of Kystle is a very specific exception. He knows what's in store for it if he doesn't do anything. Genocide for the invaders (Lynn would call it justified, he just thinks murder is murder), a second invasion of New Kystle, immortal psychopaths with sharp weaponry running around - not the kinds of things he wants. So Prime is thinking of ways to circumvent the problem.
It's unfortunately humbling when he finds no moral solution knocking at his door. There are plenty of immoral ones, but he doesn't touch those. Certainly, he could throw the out of work demon hunters at the plane, tell them to kill things, but that hardly solves the underlying problem. Even he, with all his power, can't save an entire planet. His sister couldn't, either. Not even both of them together.
Obviously, he needs more resources. He didn't deal much in other planes, not when the risks were so great. But now - now he knows that there are other versions of him, other versions of Bells. With various types of magic. Prime isn't a greedy man, but he knows new possible resources when he sees hints of them, and he wants them. He can fix - not his mistake in particular, but his mother's, the second bloodline's.
He spends some time scrying, and then he sighs and snaps his eyes shut. Yeah, that's definitely something. He did not need to see a younger version of himself having sex. Ever. Annoying how his alts seem to come in pairs with 'Bells,' it leads to awkward situations like this. Mirrors are retrieved, and then Prime informs everyone of what he's found - another Adarin, another Bell, together and obviously with some kind of magic.
Since Pantheon seems to be their impromptu central base, he retrieves a recent creation of his, and off he goes to meet with Spring. They're going to write a letter.
