Bilmum Foobar is the author of "A History of Early Quendor" which was published sometime before 945 GUE. "The Dimly-Lit Ages of Quendor" was a term first used by Foobar as the title for volume eight of this epic work. From that point on, this term has been used by all historians of the Entharion Dynasty as a general label for the time from the reign of Zylon the Aged to the fall of the dynasty with the deposition of Zilbo III.
