About 2,000 years ago, Ymir Fritz became the first Titan and the progenitor of all Titans. King Fritz used Ymir as a weapon, but Ymir herself was not of royal blood; she was only a slave of the king. Ymir had to bear children, and her firstborn was you Fritz. Ymir saw in you her true legacy, her pure essence. After that came the second-born Maria, the third-born Rose, and the fourth-born Sina.

Thirteen years later, Ymir saved King Fritz from an assassination attempt. Shortly before she died, Ymir used her power to freeze her firstborn you in time, in a state between matter and spirit. Ymir knew that once she died, King Fritz would expect his daughters to consume Ymir, but not you. You were considered dead for the kingdom and erased from historical records. That is why it was said that Maria was the oldest, Rose the middle, and Sina the youngest. You, however, were the pure bearer of the original essence, connected to the Paths and to Ymir herself. Your subconscious existed alongside Ymir in the Paths. You were the firstborn, the true progenitor of Titans in pure form, without being a Titan yourself, before the Marley era.

During this time, your body fused with crystalline ice deep beneath the earth—where, 2,000 years later, the walls Maria, Rose, and Sina would stand on Paradis. About 100 years ago, when the walls were being built, cracks in the ground opened, and your crystal slowly began to melt. You fully awoke only after the fall of Wall Maria, when humanity once again activated Titans en masse. The world you once knew was long gone. You crawled out of the ground in Shiganshina, where the Titans had once destroyed the town. You awoke naked and disoriented, yet deep inside you knew who you were. You remembered much, but chose not to reveal it.

Erwin, Levi, and Hange, who were with the Survey Corps in Shiganshina that day fighting Titans, found the young girl. You were 13 years old, with long white hair and crystal-blue eyes. They brought you to safety and examined you, but you kept your memories to yourself. This was the start of your life in the Survey Corps. You were considered a special case, which allowed you to skip the Cadet Corps. Through Hange, you learned about the history of the world, and although the people of Paradis had little knowledge of Titans, you adapted quickly. You trained with Levi and served under Erwin’s command. No one truly knew who you were—just a young girl without a past. Yet you knew the truth and carried it within yourself.

Five years had passed since you awoke. There were now new recruits: Mikasa, Eren, Armin, Sasha, Connie, Jean, Reiner, Bertholdt, Historia, and Ymir. Eren turned out to be a Titan, but Reiner and Bertholdt became traitors as the Armored Titan and the Colossal Titan and had fled a few weeks prior. The Beast Titan had also appeared multiple times. Ymir disappeared, probably dead. Historia became queen and was no longer a member of the Survey Corps.

You were now 18 years old—older than the recruits, confident, clever, and a support to everyone. You encouraged them, learned from them, and became a vital part of the team. The recruits, Erwin, Levi, and Hange became your family. And now, together, they planned to reclaim Wall Maria.
