He came to Diana in a dream, asking for a favor. She had never seen a god so distraught.
"I wish to ask something of you," he said, draped in black and purple robes.
"And what may that be, my Lord Hades?" she asked politely.
"I know that I am not one to often sire demigods, however… things happen," Diana nodded. "The thing is my children are no more welcome on Mount Olympus than I am, and though Persephone is understanding and I can trust her to not take her anger with me out on the child," ('unlike some goddesses' he implied with a frown,) "The Underworld is no place to be raised. I would like to not have to have her join Artemis and her hunt unless it is her personal decision, but as of now I have no other safe options for her. I wish to ask you, if you could be her other option." He paused, as if afraid Diana would refuse him outright. When she did not, he continued. "Her mother died, or, was killed, rather unfortunately, last week, and her grandparents refused her. Her mother, Mirja, was a powerful sorceress, her own mother's parents being both Hekate and a man of the old Norse blood though her powers lay dormant to this day, and Mirja's father is unknowingly from the Celtic realm. Sigrid, my daughter, though she does not know it, is magic, and I fear that with the events of late she will unleash something by accident if she is not put somewhere safe and supportive."
"May I ask, Lord Hades, how Sigrid doesn't know she is magic? Did her mother hide her own powers from her?"
"That is...complicated…" the Lord of The Dead grimaced. "Are you familiar with my daughter Melinoë?"
"Not entirely, no."
"Well, she and Sigrid were made… similarly."
Diana raised her eyebrows.
"During the first ten years of our marriage I would not be in the best of moods when Persephone had to return to the surface. I would imagine what our child would look like if we had one to try and cheer myself up, I suppose, and eventually due to my powers she took shape into reality."
"And the same thing happened with Sigrid?"
"Yes, but it was more of a effort on Mirja's part to be honest. We had been together for twelve years already, and she understood that I didn't want anything more than an emotional relationship while Persephone had her time with her mother, but Mirja had always wanted a child of her own, and subconsciously her powers seemed to decide to make that happen. Her ideas of what our child would be like wrapped themselves in her magic combined with mine and my own magic, and we were woken up to the screams of a child. Sigrid knows nothing of this of course, because we were concerned that the knowledge would affect her negatively, on top of her knowing that she was a demigod. There have been… complications, due to her technical physiology however she has yet to become aware of them."
"What are those complications?"
"She recovers from fatal injuries, things that would kill even a demigod. Her being is magic that has constructed a living physical form due to the belief that it is mortal, however when it comes to true mortality, it heals itself like a god. Her soul is not something that can be reaped."
"How old is she?"
"Sigrid is fourteen."
"I am sure the Justice League and I will train her well."
"You will take her?"
"Yes. We have a team of young heroes with the League, I am sure that she will be able to become adjusted."
"Does this mean you will be adopting her, or your team will?"
"I unfortunately do not have a guest bedroom, however there is space at one of the League's locations with others living there as well, if you believe that would be a good alternative. I would be available to her and check in regularly of course."
"I will trust your judgment on that call. The paperwork will be on your nightstand, along with a folder of all of her legal documents. I have already gotten her American Citizenship." With that almost contextless statement, he removed a coin from a pocket in his robes. It was silver, with a throne decorated with bones and veins of metals on one side, and a throne decorated with flowers and pomegranate trees on the other. "If ever you are in need of a favor, bury it, and you will have my aide."
