Urianger has located the Lightwarden of Il Mheg and will assist you in dealing with the pixies to reach its location.

Requirements

This quest is available if you have completed the quest Unto the Truth.

Starting the Quest

Talk to Urianger in Il Mheg to begin the quest.

Use the Sharlayan Box to Capture a Weakened Hawker

Go outside and go to one of the quest icons on the map. Weaken, but don't kill, a Hawker. When its health is low, make sure you are targeting it, and use the Sharlayan box on it from the Key Items section of your inventory, or you can target it and use the icon to the right of the quest name in your list of active quests.

Deliver the Boxed Hawker to Urianger

Go back into the building and go to the quest icon on the map. Talk to Urianger to hand over the Boxed Hawker. 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.

Speak with Sul Uin

Go south to where the orange arrow is pointing in the minimap. Talk to Sul Uin to complete the quest.

Next Main Scenario Quest

After you complete the quest, you will need to be at least level 73 to proceed to the next quest. After you reach level 73, talk to Sul Uin to accept the next quest: The Key to the Castle. There will be a cutscene.
