Return to Highlord Tirion Fordring at Crusaders' Pinnacle with news of Emerald Acorn's effects.
I feel refreshed... renewed... but the plague still grips me. Not to worry, I am still eternally grateful that you went to such lengths for me, a complete stranger. If nothing else, you've bought me a few more precious hours not plaguing the world as a hideous undead.
Thank you, <class>. Please extend my thanks to Tirion as well, and let him know that it has been an honor to serve beside him.
