Castle in the Sky Walkthrough

Jacul Ire (Huge Thing) Location

# Walkthrough
1
To start the Castle in the Sky mission, you must first complete Chapter 4. Speak to Kuta, located at the Cleansing Spring in Sylvalum. You can easily reach it by fast traveling to FN Site 417 and heading southeast.

Kuta only appears at nighttime, between 7:00 PM and 5:00 AM, so adjust the time accordingly.

2
After accepting the mission, your next objective is to retrieve Kuta’s lost cargo, which was taken by some kind of huge thing.

Before heading out, make sure to talk to Wanana and Nana, and yes, it still needs to be nighttime, or they won’t appear.
3 Time to hunt down that huge thing, turns out it's a Jacul Ire.

Follow the quest marker to the South Ciel Sandsea. You can fast travel to FN Site 408 to reach the area more quickly.
4
The Jacul Ire is marked on your map, but spotting it isn’t easy because it’s a flying enemy, so tilt your camera up and target lock enemies until you find a Level 32 Jacul Ire roaming the skies.
5
After defeating the Jacul Ire and retrieving Kuta’s cargo, return to the Cleansing Spring and hand it back to Kuta again at nighttime to complete the mission.
