Well, Ymir was born from the void in Norse lore. Ymir's body was used to create the world as we know it in the mythology. For example, the mountains were made from her bones, the seas from her blood. Her back story is crucial as it sets the foundation for the entire Norse cosmological view.
One key element is definitely Ymir's emergence from the chaos of Ginnungagap. Then there's the significance of his body being used to form the world. His bones for mountains, his flesh for land, all these are important elements that show how the Norse believed the world was created from this one giant being. It also implies a certain hierarchy in the cosmos as the later - arriving gods were the ones who shaped the world from Ymir.
In a fanfic, Christa and Ymir might find a hidden place within the walls. This place has secrets about the origin of the Titans. As they explore it, they learn more about each other. Christa could discover Ymir's past and understand why she is the way she is. Their story could be filled with mystery and adventure, and in the end, they become even closer friends.
One common theme is friendship. Many fanfictions focus on how Ymir and Sasha form a strong bond through shared experiences. Another theme is growth. They often grow as individuals while also growing closer to each other.
The key elements in Ymir's back story include her emergence from the primordial state, which was a time of nothingness and potential. Her physical body being the raw material for the creation of the world, like the sky, the earth, and the seas. And finally, the act of the gods overpowering her, which is a significant part of the power dynamic in Norse mythology.
Ymir is often considered the first being in Norse mythology. According to the origin story, Ymir emerged from the primordial chaos, specifically from the place where ice and fire met in Ginnungagap. Ymir was a giant, and from his body, other elements of the Norse cosmos were created. For example, his sweat became the sea, his bones became mountains, and his hair became trees. This origin story is fundamental in understanding the Norse view of creation and the relationships between different elements in their cosmology.
Their relationship can also be seen as a form of mutual dependence. Christa, on the other hand, gives Ymir a sense of purpose. She is like a light in Ymir's somewhat dark world. Through their interactions, we can explore themes like loyalty, self - discovery, and the power of friendship in the context of the 'Attack on Titan' universe.
The theme of identity also plays a big role. Christa has her own identity issues, and Ymir helps her to face and understand herself better. At the same time, Ymir's own identity is also explored through her relationship with Christa. It's like they are both on a journey of self - discovery together.
In fanfiction, the relationship between Eren and Ymir can be very complex. Some fanfictions might explore how Eren's actions are influenced by Ymir's power and history. For example, they could depict Eren as trying to understand Ymir's true intentions behind the power of the Titans. It might also show how Ymir views Eren's determination and how that might play into the overall story of the Attack on Titan universe within the fan - created narrative.
