Summary
“Uh, Hiruko? Did you bite your lip or something? You’re… bleeding.”
Before she can respond, he hears a familiar shout from behind him, and turns to see Hiruko limping closer, clutching her stomach as red drips between her fingers.
It takes him all too long to realize the discrepancy, and where he’d seen that exact shade of starry, ink-black fluid before.
Takumi makes a different decision, and sees a whole new side of the war.
Takes place during the Box Of Blessings route.

Summary
A girl grew up in a small village in Ordelia territory, under the tutelage of an oddly intelligent woman. While living in silence, she happened to meet two strange individuals. One was a gruffy old man who seemed to know events that happened several centuries ago. The other was a boy whose voice was monotone and expression was frozen solid.
This chance encounter would eventually morph into a much bigger case, one that could reshape the history of Fodlan itself.
This fiction is my rewrite of Silver Snow plot by adding elements of Warriors Three Hopes and giving Byleth a bigger light in the plot. Give me any feedback and criticism if I am doing it wrong.

On the Beach of Beginnings, a green chalcedony is born. They fall from the cliff face, and are badly damaged, assumed not to have survived the fall until they ask a yellow-haired gem named Sulfur, whose job is to watch over newborn gems, to help them. The sun is setting, and against their better judgement, Sulfur carries the newborn back to the temple... to be reborn again. Placed in the capable yet deranged hands of Rutile and used as part of an unethical science experiment, who will this anomaly of a newborn turn out to be?
