This is where you will find the gate, it is originally locked. You can purchase the Graveyard Key from the Moogle Vendor. Once you return with the key you can use it on the gate and it opens up. However, at first, there is nothing here. There’s no treasure chests, no loot, no enemies to fight, it’s a large, open, blank space that offers no reward for spending your Moogle Medals on the key.
If you keep progressing through the area, completing side quests, you will unlock quest 12. Paying Respects. An elderly gentleman outside the Weapons Store tells you that he wants to visit his wifes grave but it has been overrun by monsters. That’s when you can use the key to access the Graveyard, it’s just an item used to complete a quest.
