In Norse creation mythology, Ymir is a primordial giant and the first being born from the melted ice. He is considered the ancestor of all giants and is characterized by his immense size and the ability to produce life. From Ymir's body, the world was created: his flesh became the land, his blood the oceans, and his bones the mountains. Additionally, he was a source of conflict, as his death led to the formation of Midgard, or the world inhabited by humans, highlighting the cycle of creation and destruction.
