The person, while you are waiting, passes you a crystal that pulses with warmth to hold or put in your pocket. It warms most of your body upon any skin contact, you find, just enough to stave off the shivering. They do not seem at any point in any discomfort from the temperature.
When Inara tells them to make their case, they fidget with one of their small crystals, flipping it against their palm with their thumb.
"You must understand, I awoke alone in a world made of crystal. I had no body, nor any recollection of my exile there, and for what must have been millennium I wandered there in the manner of a spirit or a puff of wind. It took this long to realize that any manner of change was possible, and even longer to fully understand the methods."
"The crystals that my world was made of can be traded with matter from other worlds. See, I can prove this, here..."
They take up a stone, one slick with frost. Slowly in their hand, it blanches to white, and then it becomes clear crystal, catching the light and glittering madly, as it splits the light and bends it into several colors onto the snow.
A moment later, it starts to slowly regain opacity and color, but this time it is black, and a chunk of charcoal sits in their hand of the same shape, once it is fully formed.
"It took some blind striking around with this before I fully learned how to use it to my benefit; in the expanse of space there is a whole lot of... nothing. But I got lucky quite a few times, and I was able to bring a small beetle to my world. There, I could split my consciousness with it, and walk around amongst the crystals with the body of the beetle. I sent it back to its own world, and tried to escape through it, but the manner of my exile kept me in my world of crystal. I could only be a spectator in its life for many days until I learnt to influence it somewhat, and through it, I brought back materials, trading them for crystals, enough to construct more things of a living sort, and thus walk through the world outside with the feet of another being."
"Finally, I managed to construct the body of a person. Made through patchworked flesh carefully gleaned from those fallen and traded for with crystals. I could bring it to life in my own world by sharing my own consciousness, though I could not bring it out into another world, since my reach outside is not enough to man a whole person alone. I had to continue my experiments with beetles and such."
"I found a way of magic in another world where life force is something shared amongst all beings that can carry it, one where all who had inhabited it had fallen dead of the sickness of the heart, greed, and the wrath borne of envy. The life-magic ran ambient through its soil, hungry for inhabitance and hungry to roam. My creatures transported there could gain their own life, and walk about with thoughts of their own as I spectated."
"They could not return to me, though. I was cursed with phrasing such that no creature together with its own life can be brought to accompany in my own world, or that is what I can discern from the things that I have and have not been able to do. I could transport my wards between other worlds, but not to my own of crystal, not without their life being left behind and I left with only their body."
"After years of more experimentation, though, I learned a way to bring life to creatures I've constructed in my own world by the transporting of life force in trace amounts from the world where it sings, through the crystals, to my own. Those living creatures can never leave my home world, though."
"So, I began to construct ecosystems there. I do careful study to fit them carefully together so that the balance is sustainable, and I have made it a beautiful place with many beautiful creatures, and all that they need with land aplenty to roam. I have many wards in different worlds who search and trade for crystal the things which in their own worlds will not be missed."
"I set a careful rule, though. In all the collecting, in all the gathering, I will kill nothing. No one. My wards, too, are strictly instructed to take utmost care to harm nothing in any world they traverse. This means that I cannot bring creatures while they live to my world, as their life would be left behind. I take only those which are already deceased, and use their bodies again, repairing them, and I give them life anew."
"Life is somewhat fragile on my world. It is carefully constructed. It must be. Every facet of it, is carefully made and studied by myself. It grieves me terribly whenever any of my beloved creations is lost before its time. I give them everything I can, but I am only one being, and sometimes I cannot see an issue before it is too late."
"I learned that a banshee can help with this. A banshee can alert me; though I am attentive myself, I lack the instinct that a banshee has, and can help me better care for the ones I love so dearly."
"I cannot transport a live one to my world. That would be to take it away from its own world. That would be to kill it. If I had one alive, my ward would care for it in its own world until it passed of a natural cause. One that has already passed away, I could take immediately. I would use its design and its flesh to recreate it in my own world, afterwards."
"There, it would be treated with care and reverence, as it would play a crucial role in my world. It would aid in the betterment of care for many others, in a place that I have made beautiful; it would lack for nothing."
