Aethelwolf's expression turned serious when he heard this. The Underworlders are cruel creatures who are fond of slaughter and bloodshed. If a huge number of them comes out to the surface, the Regalis Continent would enter a period of massacre! The only way for them to fight against those creatures was to form an alliance. Aethelwolf also knows about this and that was why he didn't hesitate to form an alliance with the Paramount Heaven Empire despite Lark Whitmond's questionable personality.
Aethelwolf took a deep breath to calm down before he answered. "I will be there, but what about the exploration of the Frigid Snow Dimension?" This was something important since he wanted to see if he could find something valuable in the pocket dimension. He might even find an item that was capable of unsealing the ancestor of the Ancient Fairies!
