Story Mission quest

After beating the boss in the new moon palace the boss.i skip the conversation now when i look at my quest there are no quest so guys help me the boss mentioned to go to a castle ,
what castle is it?

 

This is the New Moon Palace/Nehelo Swamp Quest info.

Spoiler: Quest details

You meet the supposed Holy Gem merchant in the Nehelo Swamp after helping the butler with Ooze and an abduction case. He tells you to get a proof from the New Moon Palace. That's the map after the swamp.
You then head to the palace where guards stop you from advancing. You then realize they are the same people who appeared previously when you were at the Ruined Temple,about to fight the Minotaur. They tell you about the Three Trials of the palace and starts the next part of the story.
[Entrance :] You have to collect 10 of each (Swordsman and Mage) Stone Coins to enter through the gate into the 1st chamber. (Only needs to be done ONCE)
[Trial 1 :] You then enter and proceed to make your way to the 2nd chamber,but there's a magic barrier blocking the path to it. You would then have to collect 20 Swordsman Stone Coins to proceed. (Again,only needs to be done ONCE)
[Trial 2 :] You then enter the 2nd chamber,where there is a puzzle. You will have to press down some magic sensors and make a dash to the finish before you get rejected by another barrier and have to restart. (Only needs to be done ONCE...yet again)
[Trial 3 :] You then enter the last chamber. A mage clad in gold armor known as Mauez,the Moon Wizard awaits your arrival. He monologues about his past and explains the full gold armor,which is actually a life sustaining device. He had sustained heavy injuries (His arm was lost,and something else I can't remember) while trying to seal up a gate with a few other wizards. (Pardon my fogginess at this part,didn't pay much attention to it) You then proceed to spar with him.
(Since Mauez is a boss,the quest only needs you to win him ONCE. You can rematch him anytime.)
*Side note : Mauez has one of my favorite battle themes.
[Completion :] Mauez hands you the Proof Of Victory,supposedly a quest item but nope! It is a talisman that comes with a natural 2 slots. You then rush back to Nehelo to meet up with the Holy Gem merchant,but he presumably tricked you and ran away. The current Main Quest storyline also ends here as a cliffhanger.

Also there was never a mention of a castle at the end,only return to the merchant,followed by this line...

Spoiler: The line
