Marrying The Fake Invalid Dragon Lord

“I was the legitimate first daughter of House Griffith, but my father shattered my Dragon Core, turning me into a worthless "Dragonless." I thought my family still cared, until my half-sister Gale visited me in the dungeon to feed me the "Soul's Extinction" poison. As the poison burned away my very soul, she stood in her royal gown and laughed. "Your fiancé has been with me for months," she smiled, twisting the knife. She revealed that my own father had orchestrated my downfall because he didn't want a weak daughter tarnishing his name. Even my little brother had been brainwashed into believing I caused our mother's death. My entire family had conspired to erase my existence, ensuring nothing was left of me to even fade into memory. I writhed on the filthy straw, my vocal cords severed by the poison, unable to even scream. Why? I was the daughter of a legendary Dragon Marshal, yet I was treated worse than a stray dog. As darkness swallowed me whole, my eyes burned with a hatred so intense it felt like magma. If there is another life, I swear I will make them beg for a death as simple as this. The pain vanished. I gasped and opened my eyes. I was back in my bedroom at age fifteen, on the exact day my sister sent a drunken noble to ruin me. I didn't cower. I picked up a heavy iron poker from the hearth. My revenge starts now.”
