Look, dearie, I've had a dream. It's be possible for you to show yourself off to whole new worlds. It's a bit of a funny motion, but if you sort of wiggle like this- See? That's a channel your radiance can fill without just getting lost in the Beyond.
What are you doing? Incarnating an outsider is one thing, but giving it all these high-end custom powers is definitely not allowed. And even if it was you don't have enough intervention budget for this kind of custom miracle, especially unprompted. And you still haven't even chosen domains or a holy symbol! If you're not going to abide by the contract, just save everyone the trouble and say so now.
But don't you see, Creation will end unless I bring this specific former-mortal into it. Nethys knows why.
Creation doesn't usually end when foreign gods show up, but foreign gods don't usually show up. It's been happening a lot more recently, though. I've heard of these two before, they're fun.
Oh, that. Here, I'll pay for part of it. She won't break the world any worse than it already is, she'll live in the world after all. And I want to taste new flavors of magic!
That's probably for the best. It gives her a chance to try lower-stakes things before the higher-stakes ones.
This is still going to eat up almost all of her intervention budget for... A while. But that's fine. She'll watch, and learn, and maybe occasionally drop hints.
