A sealed door.

There are eight sealed doors located around the Lucian frontier, and behind each on slumbers a ferocious fiend that attacked the realm in ancient times. As the latter-day king, it is Noctis's royal duty to eliminate the menaces once and for all.
—Quest Description

Menace Beneath Lucis is a sidequest in Final Fantasy XV. It becomes available by defeating the game and continuing to play into Chapter 15. The player must also collect the royal arms from the following dungeons: Costlemark Tower, Crestholm Channels, Balouve Mines and the Daurell Caverns. Once these conditions have been met, one must travel to Meldacio Hunter HQ southeast of the Vesperpool to meet an elderly women named Ezma Auburnbrie sat outside the diner. She will hand Noctis the Sealbreakers Key, a mystical key used to seal away a great evil, said to be forged by a Lucian king and an Oracle of yore. The key does not carry over to New Game Plus or when using chapter select.



Ezma yields the key to the sealed doors.

The sealed doors conceal a tremendous danger behind each one of them. When they were created is unknown, but the key to them was said to have been forged by a king and an Oracle long ago. According to Ezma, the doors were only a temporary solution and would eventually break. Knowing this, she waited for someone she thought capable of destroying the monsters behind the doors to entrust the key to them.

Regis Lucis Caelum had met Ezma during his journey 30 years ago. Ezma believed Regis could destroy the monsters, but due to the circumstances of his journey, he was unable to. He promised he would take the task when the war with Niflheim was over. When Niflheim decimated Insomnia, this promise was thought to be lost, but Prince Noctis, Regis's son, would end up fulfilling it unknowingly.


The party receives eight quests to travel throughout Lucis and defeat the mini-bosses at the end of each dungeon. The Sealbreaker opens the sealed doors in eight different dungeons:

Completing all eight quests rewards the player with the Hunter's Medal Treasure.
