When they finally catch up with the giant snake it lies exhausted, its mouth forced wide open by a giant magic mirror. Aria tries talking to it, but the poor thing can only think of how tired and hurt and hungry it is. So they try to remove the mirror as gently as they can, Aria opening the snake's mouth just a little further while Tora tries to push the mirror out sideways, but her grip slips and they touch the reflective surface and -
"We would be happy to help! Though we are not sure our power can go beyond Amphoreus. But if anyone can get you home, that'd us! Or maybe Naxy. He can do many things we don't understand."
"Oh! We would like to talk with Tora! Are we not speaking your language? You are speaking ours!"
"I have Tongues, a translation spell that lets me understand and speak any language. You're not speaking one that I recognize." Beastspeak on Tora.
"Then please accept this spell, it will share the language with you for twenty-four hours." Not that she could land anything hostile on a demigod, if this really is one.
Share Language.
"It's... a normal second circle spell?"
Well, she's clearly not a demigod (not that that was very probable), but at least they'll hear her whole story. She updates Tora quickly on what's been said so far.
"A god gave you their power because they feared going mad? What's driving the gods mad?"
Tora is better than she is at taking things at face value and asking reasonable-sounding questions instead of questioning ridiculous-sounding answers!
"The black tide. Nobody knows where really came from, but it's been corrupting the land, people, and even Titans. It's why we must recover the coreflames and the world."
"What's this corruption like? We have some kinds of corruption on Golarion but I haven't seen them myself."
"The land gets twisted, blackened. The people first go mad and attack everyone they can see, then they lose themselves completely, and their bodies turn to something metallic, and deadly."
"That sounds terrible. And none of your gods and wizards and so on understand it, or can fight it?"
"And your druids?" If the very land is being corrupted that's clearly a matter for the druids.
If this story is remotely true the local druids will in fact be already working on it, but druids often have good reason to remain hidden. Tora is very lucky to have lived all her life in a land whose druids can walk openly in safety outside the forest. That's another thing the treaty bought them, not that they particularly cared about it at the time.
(Aria is admittedly unsure about the presence of druids on planes besides the Material, but in a normal-seeming world why wouldn't there be druids?)
"The Grove of Epiphany, the academy built around Cerces, Titan of Reason, has been studying the black tide, and Kephale's miracles can sometimes cleanse the land if the corruption isn't too strong yet. Yet the only hope we have of truly cleansing the world is the miracle of genesis. We asked Janus back then, and they only echoed Kephale's words."
"It is Kephale's prophecy, but needs all twelve coreflames, so we think it's all of them at once."
"Kephale only conveyed the prophecy after the black tide already started affecting the Titans. We aren't sure why... And not all titans are as cooperative with humans as Kephale or Janus. I don't think we'd ever get coreflames of Strife or Sky without a fight..."
They have no reason to trust either her story or her intentions, and no way to know if the story is at all plausible.
She's saying she'd be happy to help them get home, and that she only wants to bring them somewhere safe right now. Should they put themselves in the power of the first powerful stranger they meet? Instinct and wisdom both say no. Whatever danger these statue-creatures pose, they are unlikely to be able both to fly and to borrow into the ground; Aria and Tora can escape them and make their own way.
"Can you give us directions to Okhema? I would like to explore this new land on the way there, to orient myself. And if you have more information to share on the abilities of these statues, that would be most appreciated."
"Well, finding Okhema is easy! Just keep Kephale in your sight!" she rattles off some directions about the easiest way to take. "Are you sure you would be safe? There shouldn't be black tide this close to Okhema, but the Strife minions can be anywhere."
"Can they fly or burrow or strike at a distance? Do they all look like these statues? If they can't and they do, then I think we'll be fine."
"They have archers, and some can fly. We haven't heard of any that burrow. Their bodies are stone."
