An invasion of a Mansion by some weasels foretells both joy and sorrow for a former ruler; meanwhile the crash of a tree near the Hill Palace causes a character in this work to command his men to stand ever-ready to shoot the goblins thought to be responsible.  Earlier in this work that same character's cruelty causes the dancing girl Gio to shave her head and become a nun.  Originally divided into twelve chapters, later versions included a secret text known as "The Initiates' Chapter" which focuses on the "Matter of the Six Paths" and tells the story of an Empress' exile.  Other episodes include a Prince leading a fruitless revolt alongside the monks of Miiidera, as well as the execution of the child warrior Atsumori by Kumagae.  Although the ruthless Kiyomori leads the title group to a series of victories in the early chapters, the defeat of  Rokudai at the battle of Dan-no-Ura cements their demise. For 10 points, identify this work set during the Gempei Wars, a Japanese epic that traces the decline of the Taira clan.
