After you salvage the fallen cargo from the overturned wagon, Luquelot in the stable needs help finding a missing egg.
Requirements
This quest is only available if you started the game in Gridania, you have completed the quest Salvaging the Scene, and have reached level 14.
Starting the Quest
Go into the stable at Bentbranch Meadows in the Central Shroud to find Luquelot, and talk to him to start the quest.
Question the People of Bentbranch
There are three destinations marked on the map and minimap. Go to each location and talk to each person with the quest icon over their head.
Speak with Luquelot
After you have talked to the three people, go back and talk to Luquelot. There will be a cutscene.
Subdue the Thief
Go south from Bentbranch Meadows, then at the fork in the road, go west. At the cliff wall, you will find Kuplu Kopo. There will be a glow around the moogle, indicating another instanced battle. Check on Kuplu and there will be a cutscene, and then the battle will ensue.
Solo Duty: Leia's Legacy
You will be faced with three Hedge Knights, and Janremi Blackheart. One of the Hedge Knights is a Healer (holding a cane instead of a bow), so you should defeat the healer first so he won't keep healing your other enemies. After that, defeat the two other Hedge Knights, then Janremi Blackheart. He can inflict Slow on you, which temporarily makes your abilites take longer to recharge.
Retrieve Leia's Egg
After the battle, talk to Kuplu Kopo and there will be a cutscene.
Return Leia's Egg
Go east, then north at the fork in the road, to return to Bentbranch Meadows, and go to Luquelot in the stable to return Leia's egg. There will be a cutscene.
Speak with Luquelot Again
After the cutscene, speak with Luquelot to complete the quest.
Next Main Scenario Quest
After completing the quest, talk to Luquelot to accept the next quest: Dread Is in the Air.
