Walkthrough
Take Gwen and other heroes and leave from Nolani Academy. This area will now be filled with level 20 Charr as they appear in the Charr Homelands, however they aren't as large in groups so you have a better chance. Follow the quest marker to the ruins and carefully begin to pick off the Charr groups from a distance. The ranger Charr boss is still the same level he allways was so he's an easy morale boost if you need it. This shouldn't cause any major problems, even with 1 healer, if you have someone who can attack at range, it will help greatly in taking out Charr from where they cannot get to you thanks to the map layout.

Upon defeating the Charr you'll free Duke Barradin and Farrah Cappo who will lead you inform you of the new boss in Old Ascalon. Leave from Serenity Temple and go south, taking out the Charr carefully as you go (They are level 20 here too). The boss is lightly guarded and can be taken out without many problems. Once you do this, Gwen will take you to where the farmer kept his pigs in Ashford and ask you to kneel and search for something. Doing this gives you Gwen's Flute (Unique Item) and a conversation with Gwen about her friendship with the character. To end the quest, talk to the Duke in Piken Square.

Trivia

 * The flute she gives you is supposedly the same one the player gave to Gwen in Pre-Searing, only now it's become a mesmer focus.
 * She will remove the Tapestry Shred from your inventory upon accepting this quest, do not abandon this quest unless you are prepared to get another!
 * This quest answers one of the most widely speculated parts of Guild Wars, "What was the point of the items linked to Gwen?".
