Book 1 - Behind the Undeads/Chapter 2

Next day, King Lathas saw the origami plane on his throne.

"Doorkeepers, whose plane is it?"

"We don't know. There is a royal seal on the plane; we dare not open it."

The king, filled with questions, cautiously unfolded the plane. Then, he saw some words on it. As he was reading what was written, the king frowned at first, then he seemed confused, and finally dropped his jaw in an unkingly manner.

"Doorkeepers, I will have a meeting with the military. You are dismissed now."

The king arrived at a seemingly uninteresting warehouse. After ensuring that there is nobody in the vicinity, the king shouted, "stupid camel, open the cursed door!" and cast a fire bolt on the door.
