"I wasn't super close to my grandma but having the option is good and a video call suffices for what I meant to ask about. Later, when I know what to ask her. What else should I know?"

"There are many things you should know. Shall I begin with the worlds you might be sent to?"

"Please."

"There are four worlds where God had revealed to me that we might send you on your holy mission.

Virata, a world where magic flows freely, for better and worse. The people are varied and not merely human, and conflict comes often. Many demons and angels both are sent to this world, where all is more intense. Here, the existence of both demons and angels is publicly known, and only the greatest miracles might outshine the acts of powerful magic-users. It would be a chaotic place, and one where more kind souls are always needed.

Nocturna, a world much like Earth in some ways- Almost a mirror of it in the curious way that worlds do. The same great nations and technologies for the most part, and the same banal evils where murders occur over shoes or bombs are dropped by men behind screens. But magic runs through Nocturna, if weakly. Demons, vampires, the Fey, and other such things- Hidden but still dangerous. The light of Heaven can do much in such a world.

Astrata, where outer space is like the oceans in earlier centuries. To be crossed in weeks or months, but only by well-fitted ships, with many dangers lurking underneath the veil that such vessels pierce to leap beyond the speed of light. A place of warring empires, isolation turning to insular conflict and economic inequality. Computers here, can only work in a limited fashion due to the laws of physics that permit FTL travel. Angels are not wholly unknown here.

Abyssia, a strange world not arranged as a sphere in void but rather as a vast column, the shaft, which seems to go on for ever both up and down. It is surrounded by caves and chambers which oft contain self-regenerating resources as well as dangerous animals and even Demons waiting to pounce, which humanity did explore eagerly. A strange place, where travel is typically only one direction- Down. Why such a world exists I know not, but their souls call for aid just as loudly."

"Why don't people ever climb up, in Abyssia?"

"That was poorly phrased. My apologies. 'Typically', is not 'only'. It's much more difficult to go up than down, so people do it less, even to access unused space far above."

"What are the like, mission parameters, for an angel in each of these worlds?"

"Simply, to do good. To make the world a better place. Your judgement on what actions accomplish that best had been better than many of the heaven-born angels. Heal the sick. Oppose evil and injustice. Find and fight Demons. Bring joy to your chosen community. Defend the meek. Teach the willing. Offer sympathy to those who had suffered. And to be a vessel and guide for the miracles of Heaven, which are best worked through Angels incarnate directing them."

"Found my own prosperous empire to project force into pockets of demon influence?" she suggests.

"If you had great care in ensuring it is a kind and good place, and not merely another of those empires which use slavery and suffering as tools of power, that would certainly be a worthy mission."

"Oh, yeah, no slavery in my empire and a minimum of suffering. How limited are computers in Astrata?"

"Digital computers in Astrata are devices fit to fill a large room, and operated by skilled technicians in tasks such as telephone routing, engineering simulations, or stellar navigation. Though positronic technologies are well developed in other respects, with the creation of robots capable of simple tasks- More akin to trained animals than computers."

"Huh, so like, Asimov-ish?"

"These, unlike Asimov's, are not sapient. I had been interested at times in the debate as to what makes a being of moral import. Much ink had been spilled over it."

"Tell me about vampires and the fey?"

"In truth, Heaven's influence upon Nocturna is limited enough that the full vista is not visible to us. Vampires need not kill to survive, this much is clear, and the Fey are rule-bound, merely to rules that few understand."

"And the magic, there and Virata?"

"Tis centered around rituals and careful preparation for Nocturna, whereas Abyssia's magic lies closer to instinctual command than arcane calculation. Virata is veritably overflowing with magic, as many types as I could list and more. Even ordinary people use magic to cook, clean, and farm. The sole magic of Astrata is the works of Heaven and Hell upon it."

"Abyssia has magic? Like besides the caves refilling with resources?"

"Yes, but more akin to your Foundations and Blessings than active spells, which are akin to Miracles. These are passive effects that can be cultivated- Unusual strength, keenness of senses, or lightness of foot, or perhaps a preternatural ability to sense potential profit, or detect lies."

"Huh. Can I hear about the other stuff before I pick a world?"

"Of course. Any of your choices may be changed at any time until I have begun crafting your angelic form, should you accept. And you may yet change your mind and enter the Gates instead. Perhaps Vows next. All mortal-born angels must take at least one Vow. Any Vows you choose to take will grant you greater strength, and will be built into your new form such that you literally cannot break them. An anchor like this, a core of unbreakable law, is necessary for all the other properties of an angel to bloom from."

"That sounds awfully questionable. Can you give me some examples?"

"The vow of Honesty; You cannot communicate lies in any way. You can still imply untruths and withhold certain facts, or refuse to speak on a matter. The vow of Honor; You cannot deliberately harm a being that is not aware you mean to hurt them, without a warning, not even Demons. The vow of Compassion; You cannot inflict pain for the sake of inflicting pain. If the pain serves a purpose, it does not violate this vow. There are more."

"There are people going around calling themselves angels who inflict pain for the sake of it??"
