Skydream was an Ice Worm born in the Northern part of the continent. When he was 30 years old, he happened to hide from an enemy and fell into an ice crack which happened to have 10,000 year old ice essence. Thus, he entered into a deep slumber for 10,000 years absorbing all of the ice essences within the ice cave.

While searching for a way out he found more such ice caves and thus entered into more deep slumbers absorbing all of the essences from the caves. After reaching 100,000 year of cultivation, he became a Gold-patterned Ice Worm and searched for more areas where he couldn't traverse before. He ate and slept until he had no more to absorb. He arrived in the middle of the ocean having become a 900,000 year old spirit beast.
