After you report Leonnie's lateness to Armelle, she needs you to salvage cargo from a wreckage.
This quest is only available if you started the game in Gridania, and you have completed the quest A Hearer is Often Late.
Starting the Quest
Talk to Armelle in the Central Shroud to begin the quest.
Salvage the Cargo
Go south to the location marked on the map and minimap. There is an ominous purple circle surrounding an overturned wagon and two Fallen Cargo. If you walk into the circle, a Lumber Toad attacks. Slay it, then check on the two Fallen Cargo to take them.
Deliver the Cargo
Go north to Bentbranch Meadows and talk to Keitha at the stable. Hand over the Fallen Cargo to complete the quest.
Next Main Scenario Quest
After completing the quest, you will need to be at least level 14 to proceed to the next quest. After you reach level 14, go into the stable at Bentbranch Meadows in the Central Shroud to find Luquelot, and talk to him to start the next quest: Leia's Legacy.
