Alice's search has been successful, and she has already sent a letter to the duke about her findings. All seemed to go well until someone else decided to interfere in her work, and it happened to be a member of the royal family of everyone else.
The second princess of the Brightwing Empire, Arika Brightwing, was sent here by her older sister to check for any suspicious activity in the dungeon.
This is because the dungeon is located near the City of Wings, and all dungeons around the city are of common rank.
But the empire received information about the duke deploying a large force to clear a low-ranking dungeon.
It made her sister suspicious that the duke might be planning something, and she wasn't happy about it.
Arika was forced to listen to her older sister, after all, her sister wasn't called the Brain of the Empire for nothing.
