After you have honored the custom of Mord Souq, you report back to Cassard.
This quest is available if you have completed the quest City of the Mord.
Starting the Quest
Talk to Cassard in Amh Araeng to begin the quest.
Use the Market Receipt to Collect Cassard's Purchases
To review the market receipt, you can either use the Market Receipt from the Key Items section of your inventory, or you can use the icon to the right of the quest name in your list of active quests. The market receipt is as follows:
Iron ore — Thol Tol
Nabaath Areng antiques — Mhil Mil (to be collected from Mhul Mul)
Go to the northeast of the orange circle on the map and check on the sparkling Crate of Ore next to Thol Tol. Choose "Iron ore!" from the list to proceed.
Go to the north edge of the orange circle on the map and check on the sparkling Sack of Herbal Remedies next to Thon Ton.
Go to the northwest of the orange circle on the map and check on the sparkling Box of Antiquities next to Mhul Mul.
Deliver the Mord Souq Merchandise
Go southeast to where the orange circle is pointing in the minimap. Talk to Cassard to hand over the Mord Souq Merchandise and complete the quest. There will be a cutscene. This one is important, so it is recommended to watch it either now or via the Unending Journey in an inn room.
Aether Current Quest
With the completion of this quest, you can now start the blue quest "Work to Live or Live to Work" in Amh Araeng. Completing that quest will attune you to an Aether Current in this area.
Next Main Scenario Quest
After you complete the quest, talk to Tesleen to accept the next quest: A Desert Crossing.
