Alexeara Cansellarion is in his study when he gets the vision from his Goddess, which means he must have fucked up quite badly.
"Ah. That's - I don't actually know if Taldor is the size of America or the size of, like, Texas. Is this world a ball?"
Iomedae doesn't know the answer to that! She will listen expectantly to the fancy knight.
"A ball? Yes, the world is a sphere - a wizard went to the moon a long time ago and made round maps, there's one in Vigil - that's in Lastwall, which is the country Iomedae founded after the crusade. We can go back there whenever you want."
"Is there the place to be to make the world rich and end smallpox and the plague and fight Asmodeus with guns?"
"Yes. Especially the last one, you might want the church of Abadar for making the world rich and they're - a lot of them are here in Osirion but they have representatives everywhere."
Iomedae looks to Alfirin. Her own instincts are to go where the fancy knight says but she has picked up enough common sense off Alfirin to note that there is an argument against doing that, which is that they don't actually know anything at all about the fancy knight except that he says his god, who is Iomedae, told him to resurrect them.
That's Alfirin's concern too. She can ask. "Who are you and why should we believe what you say?"
Well if he's a paladin he isn't lying. But he could be lying about being a paladin. "Are you a priest of Iomedae?" Iomedae asks Nefreti.
Nefreti makes a face. "I can't explain that…nor that …not that either…that one's not even true around here…there's a sense in which we both …exist." She looks very smug to have arrived at this.
Iomedae is frowning at Nefreti and at Cansellarion. "...does being resurrected always come with knowing who resurrected you and which god they serve?"
"...Well, then it wouldn't be happening? Wizards can't do that - except Nefreti who does it because she's a cleric too."
"Wizards can use a Limited Wish," says Nefreti, "and druids can do it, though you mustn't tell them I said so. And in that case you don't learn the god, as there is none."
"....right," says Iomedae. "...I propose that I kill myself again and you have a Lawful Good priest of Iomedae raise me, if there's really such a thing, and then I'll know that it's at least true there's a Lawful Good goddess Iomedae. I will tell you enough to pay for the resurrection in advance, though."
"Wait, don't yet - what if you get raised on another planet first?" Alfirin does not want to be alone in this bewildering future Golarion either and also doesn't exactly want to chase Iomedae across time with repeated suicides.
Iomedae pauses to consider the conundrum. "I don't think that's how that works but if it is then it's...probably good, on the whole...Maybe we could give each world a short briefing before being off again."
Alfirin switches to English "But I thought you wanted to check that these people are who they say they are before telling them things that could help them take over the planet."
"I do want to do that," Iomedae says. "But if it's impossible, then I think that just means we shouldn't explain guns, and we should probably explain nitrogen fixation and smallpox inoculation and penicillin to everyone, and hope that things get kind of backwardsedly better like they are in America? I haven't thought about this very carefully yet, I was expecting to be raised by Aroden's high priest and trust Him because He's Aroden's high priest. I don't know, what do you think we should do?"
"Um - is there any way to test without dying? We could - I don't know. Maybe you're right and we should explain those things and then you can try dying and if they don't get you right back I'll do it too. But if there's any other way to check while alive we could do that instead."
"I bet there are other ways to check, I just don't know what they are because I don't actually know very much about magic. And since Aroden's - dead - I can't even count on that He'd strip me of my powers if I was accidentally helping the Asmodeans who are apparently ruling Taldor from Colorado all the way to California."
