[Geographic Knowledge] Pila Ku Jail

Quest Text Ever since Kayal Nesser NPC Knowledge escaped from prison, it's a madhouse over here.
They are all possessed by some insanity of old.

Summary You have learned about Pila Ku Jail.

Summary Putting together the pieces of Mysterious Map, eh?
I see that I have another curious adventurer.
Well, I can tell you how,
but you must know that it's just a rumor.
Even if it works, I don't know if you will be able to find the four pieces.
Still, I will tell you if you want to know.
Listen carefully.
First, place the four pieces diagonally
from left to right.
The power of the pieces will be combined.
However, you will need four different gemstones to contain this power:
Emeralds, Topaz NPC Item, Sapphire and Ruby.
All gemstones must be the best quality ones.
Once you have them,
place the gemstones,
one by one in the correct order,
diagonally from right to left.
If you have a top quality gemstone,
you can use just one instead of several.
Place the pieces of Mysterious Map
and a top quality gemstone in an X-shape,
you can produce that thing too...

Summary What? Muiquun?
Is that where Kayal is?
You're sure that's where they are?
Thank you. I'll send my soldiers right away.
