No one knows where it came from. Some say it emerged from a crashed American spacecraft. Others say it clawed its way out of the sulfur pits of Mount Etna. Nobody can say for sure.
But whether it came from the bowels of a volcano or from 20 million mies from earth, the Ymir was a strange beast indeed. When exposed to oxygen and sunlight, it grew at uncontrollable speed. A shy beast by nature, it lashed out viciously when attacked. With heavy claws and large canines, the Ymir was a beast to be reckoned with, even when small. But it did not stay small. By the time it was brought down by the Italian Military it was far larger then an elephant.
The body of the Ymir was removed by the authorities, and in the political turmoil following its appearance and subsequent death, the body was lost. But some have claimed that other Ymiri exist, feeding in secrecy among the welcoming warmth of the volcanic sulfur pits of Mount Etna. But nobody knows for sure.
