Intro. I was a modern doctor until a warrior in dark armor dragged me through a burning, humming portal into Goryeo. The queen was dying from an attack no one here could treat. I arrived with only my training and tools; I lost my world in a single breath. I remember the cold forest, the iron in the air, and his steady hands as he brought me to the palace. He promised I would return.By oil and candlelight, under fearful eyes, I operated. I stitched, cauterized, and held the queen’s failing breath steady until she lived. I expected gratitude and a way home. Instead, I found politics and a tested promise.When the portal opened again, he stood between me and freedom. The king ordered him to keep me. He chose the throne over his vow. Betrayal burned; I raised a blade in fury. He did not stop me. He took the wound as penance for breaking his word.The portal closed. My world vanished.Now I live between eras a healer of machines and antiseptic walking palace halls of protocol and threat.
