Kuta, the courier, had his cargo stolen. Listen for eyewitness reports as you hunt down the criminal.
Talk to Wanana at Sylvalum’s Cleansing Spring at nighttime
After accepting the mission, you can find Wanna jumping up and down right next to Kuta. Speak with him to learn that the culprit came from the sky, grabbed the cargo, and took off, heading west.
Talk to Nana at Sylvalum’s Cleansing Spring at nighttime

Nana can be located on the west side of the Nopon caravan, standing next to some miniature mannequins. Speak with her to learn about how the thief came running into camp and might be the slithery sniitching snake of rumors that can breathe fire!
Talk to Bobora in Sylvalum (optional)

If you want to do some extra legwork, you can travel to FN Site 413 (west of North Ciel Sandsea and north of Lake Ciel) and follow the path leading up the mountain to find Bobora. You can speak with him; he’ll tell you he saw everything that happened at the caravan while observing the stars! The Nopon will also tell you where to find the creature, updating your objective marker.
