Lineage: A modern descendant of Thors Snorreson, long after the bloodline had faded into myth.
Premise: Eira a doctor that fights death for her patients, dies at 27. It's a hero's death, a honorable death. She sacrifices herself to save a child and pregnant woman from a violent threat fights until her last breath. It was a death worthy of Valhalla, but she died in a world that no longer believes in Odin.
The Glitch: She dies while fighting in the 21st century, and the Valkyries show up. Normal standard procedure. But when they try to guide her soul to Valhalla it glitches. Its not that a modern person can't go. It's just that this specific soul, brilliant, relentless, and carries the formant legacy of Thors, refused to go. Eira fights death as a doctor so she doesn't accept her fate. Her soul and the spiritual trannsmit troubleshoots and tries to find a file location and finds one in her bloodline.

Reality: Reincarnated back into 1002AD. She is back at the house of Thors. She's a modern soul trapped in a past, navigating the world of blood and honor that she didn't belong in, armed with stubborness and memories of aa future that hasn't happenend yet. It's a second chance to her but the universe calls it a summons.
