One day, a worshipper of Ymir Fritz found her and had her play the role of the first Titan to ever exist. Now having Ymir as her name, she was treated like a goddess and was given everything she could have dreamed of.

Willy Tybur was one of the most respected men to ever live in Attack on Titan. People all over the world loved him despite being Eldian and were eager to hear anything he had to say. Therefore, they were shocked to hear what truly happened in The Great Titan War. Many believed that once the Titan Shifters turned against each other 100 years ago, Helos and the Tybur family forced Karl Fritz and many other Eldians to go to Paradis.

Karl Fritz actually chose to go to Paradis on his own, hating the history his ancestors fabricated. He worked with the Tyburs to make sure that the Titan powers would be stripped away from the other families that abused their abilities in The Great Titan War, and Helos never truly existed. Everything that people knew about how The Great Titan War started was a lie.

Chronologically, the first half of Chapter 122, "From You, 2,000 Years Ago," is the first thing to happen in Attack on Titan. Ymir was a slave to King Fritz and after letting one of his pigs go, was hunted down. She ended up going inside of a tree that the Source of All Living Matter resided in. Upon contact with it, she became a Titan. King Fritz married her and the two of them had three daughters. He also had Ymir defeat his enemies.

However, when one of them tried to assassinate him, Ymir sacrificed herself to save him, ending her life thirteen years after she was hunted down.

The Nine Titans have always been important throughout Attack on Titan's history, and even towards the end of the story, more about their abilities was revealed. After Falco drank Zeke's spinal fluid and inherited the Jaw Titan, he had a memory of a previous inheritor of the Beast Titan, one that was able to fly.

Because of this, he and Gabi asked Annie if it was true that the Female Titan could obtain powers of the other Nine Titans. Once she confirmed this, Falco realized that he'd be able to fly, which basically made him a mix between two of the Nine Titans.

1 Zeke Explains How Life Began In Chapter 137

Armin and Zeke

Inside of the coordinate, Zeke told Armin how life began. It was the first thing to ever survive in the universe due to it constantly multiplying itself. Through multiplying, life became many different things, including people, animals, and plants. Because dying was ultimately the opposite of multiplying as it removed part of life and Ymir Fritz was too powerful to die mentally, she ended up inside of the coordinate, where she became a prisoner for centuries.

Despite knowing a lot about how life began, Zeke didn't know the meaning behind it, which Armin was able to explain to him, proving that just because life's purpose was to multiply, they could live for more than that.
