When King Smuturos of the Landder Zwerge heard about the chaos caused by the Wyvern and the group that defeated it, he immediately developed a deep interest in Castiel's group.
He wanted to meet or at least see them in person to express his gratitude. Beyond that, he also wished to establish a deeper connection with the group if possible.
The kingdom promptly sent a letter inviting Castiel's group to the palace.
Early in the morning, Castiel and his friends woke up and went downstairs to the inn to have breakfast. Upon descending, the innkeeper greeted them warmly and handed Castiel a letter bearing the kingdom's seal.
Castiel and his friends exchanged puzzled looks as they accepted the letter.
"What is this?" Castiel asked politely, his curiosity piqued.
"This was delivered by a soldier; he said the letter is from the kingdom itself," the innkeeper replied nervously.
"Kingdom?" Kit echoed, her eyes wide with surprise.
