There is a bar. In the bar is a young woman sitting at the counter, sipping something orange, reading from a pile of paper napkins.
Someone with rainbow light playing across her skin and clothes walks in the door, turns around to look behind her, steps out and then back in (keeping the door open), furrows her brow, summons a quick light, and says, apparently to herself, "Interesting. This isn't a realm of Oblivion."
The room through the still open door is entirely white or clear crystals, lit by soft green orbs. The woman closes the door, tilting her head, and opens it again, to the same room.
"...should it be? What is that?"
"I was in a Realm of Oblivion, and usually when there's unexpected connections to another Realm it's within that sphere. Oblivion is a set of planes. I'm unsure where this place is, though."
"The bar - who is a person - says it's called Milliways. Oh, uh, stand a bit back from me, in a five foot radius I involuntarily read minds."
"Does that count for any body part, or just the seat of consciousness? How do you define 'minds' here? Do you get surface thoughts, or memories, or someone's sensory input..."
"If you stick my hand in your range I can still read it. Surface thoughts and attended-to sensory input, involuntarily; I can do more than that but only on purpose."
"Interesting." She closes her door again. "Is that sort of power common here?"
"I don't know about Milliways but at home no, very rare. One person at a time for each of five power types, and they manifest a little differently."
"Interesting. Magic is very common where I'm from, but most people cannot peer into another's mind. You're not from Milliways, then?"
"I'm not sure anyone is, besides the bar. I got here the same way you did. What's your magic do?"
"For myself - I control light, and I have effectively absolute power over the Colored Rooms, a Realm of Oblivion that I made. I can grant mortals powers, briefly, and forge artifacts, as well as view and speak within the areas around my temples and devoted worshipers from afar. For my world - magic's ultimate expression created our universe. Most mortals manage fairly minor spells - healing, illusions, and conjuration of spirits or beings from outside their Realm."
"That's a whole lot of things. Mortals? You aren't a mortal?"
"No. Many beings in Oblivion aren't."
"What are you instead?"
"The official category is et'Ada, those spirits who predate our universe, Aurbis. I am one of the more powerful ones, and as such mortals consider me a Daedric Prince - loosely, Daedra are those et'Ada who did not participate in the making of the universe, and the Princes are the most powerful of them, although I am not technically a Daedra. The other two types of et'Ada are Aedra and Magna-Ge, and I am of that last group. The Aedra gave much of their power in making the universe. The Magna-Ge are those who gave some of our power and then left the project. Mortals sometimes name some of us gods, as well."
"Why are you considered a Daedric Prince if you aren't a Daedra?"
"Most Magna-Ge left Aurbis, so it's not a category mortals are very familiar with. The Aedra have their own interwoven politics and alliances and do not keep their Realms in Oblivion. The Daedra have no such alliances, and most rule within Oblivion."
"Gosh. My world doesn't seem to have gods, as far as I know. In my country we have a king, and five primes, associated with the five elements and the five aspects of people. I'm the sweela prime, fire and mind."
"Interesting. Do other countries have primes, too?"
"As far as I know they don't have anything like us."
"Do you know why?"
"How does your fire primacy manifest?"
"Do you mean what happened when I got it or what can I do?"
"The second, though the first would be interesting to know, as well."
