The summary from translator in chapter 3 is kinda wrong.
The oath letter is real, the dragon only forge the part about the gold is emergency money for the kingdom. It's actually just dirty money collected from the underworld from generations. Other than that, everything in the letter is true.
A group of meerkats is called a mob.
Now I understand why Ian thought of his classmates as meerkats (￣∇￣")
So... Senior Dilet is a girl? I always thought she is a boy when reading the novel, lol (￣∇￣")
Me too I also thought professor Garcia was male too
I even ship Dilet with Ardenath's older sister, lol~
