Ranperre's Final Rest

Details
Prince Trion seeks an adventurer. Find the prince in his chamber to learn more.

Walkthrough
After accepting the mission, talk to Prince Trion.
You are sent to King Ranperre's Tomb.
Head to H-8 on the first map and touch the door.
This will trigger 3 skeleton type NMs.
Depending on your strategy, you might want to put sneak on before spawning them to pull them one by one. It is possible to take them on at the same time if you have a strong alliance, but the safe way is definitely to pull them one by one.

Not a lot of notes on this fight, they act like normal skeletons, I think it's two Black Mage types and a fighter, so keep them silenced if you want to avoid -ga spells and keep Curaga's handy for Black Cloud. Easy fight overall. If you pull them one by one, you can get away with 6-10 people lvl60+.

After defeating them, touch the door again to receive a key item. Take this to Prince Trion.
After the cutscene, talk to a gate guard. They will tell you the deciphering of the book will take a while.
Wait about 10 real life hours and talk to Prince Trion again.
Go back to King Ranperre's Tomb to touch the door once more (No NM fight involved this time). You will get a cutscene.

Talk to the gate guard again to receive rank 7 and 40,000 gil.
