Shield of Yanshi Quest

Walkthrough

 * 1) [Optional] Speak to Royal Guard Adrana in Yanshi at 12.3S 42.4E. (It is also strongly advised to go get the 50 Repugnant Eater Kill Task from Eastwatch for 70 million more xp)
 * 2) Run due west to the Granite Quarry at 11.8S 39.0E, there is no portal, just an open entrance. Stick left until you find the Underminer Leader who drops the Underminer Notes.
 * 3) Return the notes to Adrana in Yanshi who will flag you for the next portal. (note : THIS FLAGGING IS PERMANENT and so doesn't have to be repeated)
 * 4) Return to the Granite Quarry but this time stick right to the portal to the Yanshi Lower Undermine. At the end of the lower mine is a portal to Yanshi Upper Undermine.
 * 5) Stick left and continue climbing up to the top where you'll find the Yanshi Swarm Matron that drops the Yanshi Swarm Matron's Claw.
 * 6) Return the claw to Adrana in Yanshi for the Shield of Yanshi and xp.

Lore & Dialog
Royal Guard Adrana tells you, "Ah, you might be just the person to help me. As you can see, Yanshi has been rebuilt, stronger than ever. But I suspect that there are some who are making ready to tear down all that the townsfolk have worked hard to achieve. Please travel to the nearby granite quarry at 11.8S, 39.0E and see if there are any suspicious characters about. Bring me any evidence you can find of plots against the new town."

You give Royal Guard Adrana Underminer Notes. Royal Guard Adrana tells you, "Unbelievable! Why would people willingly betray their own town to that mad dog Varicci?  It is as I feared.  Please, enter the Yanshi Lower Undermine portal at the quarry and root out the cause of this trouble.  It will not be enough to dispose of the Eaters that await -- you must fight through to the Olthoi Swarm Matron at the center of this plot and destroy her.  Bring me the matron's claw, and I will reward you."

Royal Guard Adrana tells you, "You have the claw? Give it here, please."

You give Royal Guard Adrana Yanshi Swarm Matron's Claw. Royal Guard Adrana tells you, "A crisis narrowly averted! I thank you for your bravery and loyalty to Queen Elysa.  Your actions have saved the town.  As such, I think it would be appropriate to give you the Shield of Yanshi..." You've earned 58,000,000 experience. Royal Guard Adrana tells you, "I see this is the first time you have assisted me. You did such fine work I think I should encourage you to return and aid me in the future." You've earned 15,000,000 experience. Royal Guard Adrana gives you Shield of Yanshi.
