Then Iomedae will cast a spell on herself, and grow the wings of an angel, with which she can actually fly, and she'll speak aloud for the first time, then, because angels speak every tongue in which they can be understood, and she wants to speak the tenets of Aroden's faith clearly and know that everyone heard the same thing. The spell won't persist very long, but you can't have too many tenets of your faith anyway because a lot gets lost in repetition.
In Golarion mages have used scrying and planar travel to search for the dead, and found the afterlives, and so they know what happens to you when you die. You go before the Judge, and they look at all you've done in life and send you where they think you merit it. Evil people go to the Evil afterlives, which are places of torment and cruelty, with Hell the worst of them; there they are destroyed or tormented or beaten until the humanity is burned out of them, and only the Evil - the pettiness, the cruelty, the anger - remains. Asmodeus shapes His mortals to be His slaves. He is Evil. The faith of Aroden has very few dealings with Him, all of them the dealings of enemies with temporarily shared interests.
Aroden's own domain is in Axis, Lawful Neutral, and among His reasons for choosing Axis as His domain are that it was not His desire to restrict what He could build to those of unusual virtue or merit. It is forbidden, for detailed word of the wonders of that world to come to make its way back to Golarion; it would count as interference by Aroden, if Iomedae travelled to His domain and learned the secret of the gardens that go on forever and ever, or the buildings that stand thousands of feet in the sky, if she brought that knowledge back to Golarion for people to use. And He has judged it worth it, that the people of Golarion know there are bigger things and better things, that the aim of humankind is to build a paradise beyond the imagination of the builders, for every generation to surpass the last, for things of beauty and wonder to be everywhere; but He has not judged the price worth it to tell them most of the details.
If they are Lawful when they die, and not Evil, they can go to Aroden's realm, and be united with lost loved ones who are there, and be nourished in glory and wonder forever. Or if it intolerable to them that Hell exists, that Evil exists, that the work of the world is not done, like it bothers Iomedae, they can go to Heaven, which does not content itself with building its own paradise but which also fights to bring hope and the end of Evil to everywhere else in creation. The wings she bears are a gift of Heaven.
In her world the goddess of fire and hope and redemption and the Good in every human heart is Sarenrae, and she doesn't know if that is Anathei or not, but Her paradise is called Nirvana, and Nirvana goes before the Judge to argue for every soul no matter how Evil and how damned, to argue that there is Good in that heart and a place for it in paradise, and it is a world turned towards making that true.
And in her world the goddess of exploration and wonder and freedom is Desna, and Her paradise - She'd object, here, that it's not Her paradise, just a paradise where She hangs out sometimes - is called Elysium, and there is no Law in Elysium, just the beauty and wonder wrought by everyone desiring it and building it, and there is no organized operation against Evil but a hundred million smaller ones, as everyone asks their own conscience what blows against Evil they are personally inspired to strike.
(She'll go through the other afterlives too, but in less detail; they are less important to warn people about, in her and Aroden's view of the world, and not cooperative so as she feels obliged to represent them generously as they'd do the same for her.)
The gods are ancient and inhuman. Some of them are kind, some of them are loving, some of them are generous, but they are not human, and they do not understand what it is to be human, not exactly, and in His centuries of adventures and exploration Aroden concluded that this was not the right way of things, that Creation would never permit humans to reach their true potential unless there were humans among the gods. And so He found or created the Starstone, which made gods out of men, and set protections around it, and ascended; and Irori and Nethys and Cayden Cailean and Norgorber and perhaps others have also ascended, and so very locally - because new gods are small beside the ancient gods - they are changing the balance of power in Golarion, they are making its future a future humanity chose.
And what a future humanity chooses! Wandering the plains, humans choose to befriend and domesticate animals; they choose to replant the most promising crops, until they have created entire new kinds of plants like no god imagined, just in the careful choosing. They choose writing. They choose buildings. They choose courts and laws, and myths and ballads, and heroes and teachers. They choose magic and invention and trade and prosperity and freedom. Aroden is not the god of all of those things, He couldn't be, but He is the god of civilization, that which grows to provide a foundation on which people can choose all of those things.
Iomedae does not know how directly He can intervene here. She doesn't know for sure if the souls of the dead, here, go before the Judge, or if some stranger thing happens, because Creation is very vast. But She knows that His vision is as true here as anywhere else, and that a civilization built here will have the support of every civilization across the stars aspiring to the same thing.
There are songs that are sung in the war-camps of Iomedae's world, of Aroden's vision, of mortals and what they can grow to be. Of what it is, to face challenges the gods did not ensure you could bear, to witness miracles and want to know what caused them, to grieve and know you deserve something better. She'll sing a few of them.
