After completing Dragon Quest 3 Remake's main story, there is still a formidable amount of content for players to explore. As soon as Zoma has been defeated, players will be able to return to the Castle of the Dragon Queen and begin the journey towards Cloudsgate Citadel. Found in the heavens above the first map, Cloudsgate Citadel features several important pieces of post-game content. This is where you'll find Xenlon, the immensely powerful boss that unlocks Dragon Quest 3 Remake's secret post-game dungeon, the Temple of Trials.
