As someone who came from the world of Asgard, The world of the Gods, Althea was extremely familiar with both Jormungand and Fenrir.
Jormungand has been a docile kid ever since. However, everyone fears him for his size. After all, he was so large that he was able to encircle the entire World Tree and even bite his own tail.
This achievement earned him the title of Ouroboros, representing infinity. After all, the only ones who can contend with his size, spanning an entire universe, are the Outer Gods like Azathoth and Yog-Sothoth.
Fenrir, similar to Jormungand, was another son of Loki. He, unlike his large brother, was more fierce and extremely fond of chaos and tragedy. With his eyes and nostrils blazing with fire, destruction spreads wherever he goes.
"I see." Ein nodded his head after hearing the introduction of the two from Althea. "So we can keep Jormungand and... Take care of this one?"
"...!"
