Quest rumors

Iquba al-Julmud the Barkeeper tells you, "Welcome! What's your pleasure today? How about a fried egg? Or maybe directions to a mysterious sword?"

Town Crier tells you, "...and a warrior came forth bearing the mark of Light upon him. He carried, in his hand, the rays of the sun crafted into steel. A blade with a purpose in the hands of a virtuous heart brings hope where there is none. The Light has been found again."

Town Crier tells you, "I heard from Alatar Locke recently... he was upset that he had to redo some of his oldest notes... something about some carved caves?"

Town Crier tells you, "In the Halls of Lost Light the Guardian has stirred and the sword glows brighter now than ever. Perhaps this is an omen of things to come. Perhaps it is a sign that even in this growing darkness there is still hope."
