"Now, your upgrade quest is the reason that the Butler of the Baron is here. In two days' time in the city of Blacklight, there will be a festival.
That festival is to honor our little town that has delivered an A-class labyrinth.
The Baron is going to receive recognition, and the Duke is going to award him a higher title as Viscount.
Normally, that is a privilege reserved for the King, but the King will not be in attendance, so the Duke will have to do it.
Now, this is a great ceremony, and the Baron will have to flaunt his wealth and power a bit.
That's where you come in. As the prodigy of this town and the rising star, you will be his main attendant and security for the period he stays there.
If the Baron comes back safe, your quest will be completed, and you will be promoted to B-rank, as well as given a good reward," Raze explained the quest to him.
