The Brume's residents are unwilling to provide information, so you turn to the proprietor of the Forgotten Knight.
This quest is available if you have completed the quest Ill-weather Friends.
Starting the Quest
Talk to Alphinaud in Ishgard to begin the quest.
Speak with Gibrillont
Go west. You can either go up the stairs, walk along the stone wall, and go up the next set of stairs to reach the back entrance of the Forgotten Knight, or you can use the Brume Aethernet Shard to go to the Forgotten Knight Aethernet Shard and go through the front door. Then go to the quest icon on the map and talk to Gibrillont to proceed.
Speak with the Hulking Hunter
Go up the stairs and go outside, then use the Aethernet Shard to go to the Jeweled Crozier Aethernet Shard. Go west to where the orange arrow is pointing in the minimap and talk to the Hulking Hunter to proceed.
Deliver the Fresh Herbs
Use an Aethernet Shard to go to the Forgotten Knight Aethernet Shard, then go southeast toward the quest icon on the map. Go through the double doors and down the stairs. Talk to Gibrillont and hand over the Fresh Herbs to complete the quest.
Next Main Scenario Quest
After you complete the quest, talk to Gibrillont to accept the next quest: Noble Indiscretions.
