Assuming a multiverse in which interplane-travel isn't as rare as everyone thinks, would it make sense for another setting's sun god to carry a Solar exaltation so it can be passed on to someone in that plane? The comparison is to how chosen demons carry Infernal exaltations, but without the carrier-becomes-a-UC part at the end.
Ammy (as in Okami) is just doing a favor for her four-armed counterpart and doesn't use the exaltation herself.
The second is for a crossover with Chrono Trigger/Cross. Schala Zeal, at the very end of her subplot in Trigger but before Cross can happen, instead turns away from Lavos in the Darkness Beyond Time and GTFOs like mad, eventually emerging in an interpretation of the Wyld that bleeds into the Warp, Dreaming, Nevernever, and other such regions where objective reality isn't. Then things get worse. She's almost completely out of marbles by the time she finally meets her Mate, the SI, about 20 years later.
Is this appropriate for a Lunar's origin story? I'm not sure which caste she should be, but I'm leaning towards Waning (appropriate for her debut arc) or No Moon (appropriate for her character, but creates a redundancy re: party dynamics). Full Moon is right out.
