Fall of Gurubashi is an ancient tablet that tells the tale of the end to the Gurubashi empire. It is located in the south western part of the Ruins of Zul'Kunda. [23, 12] It is in the most south western "room" (meaning walls but no roof in these ruins), in the north western corner of the room. NOTE: The tablet is in the main compound on the plateau, NOT down on the beach.
The Alliance has recently expressed interest in this particular legend. Brother Nimetz of the Rebel Camp in Stranglethorn Vale is sending adventurers to investigate many troll legends in the area in hopes of finding answers regarding Colonel Kurzen's corruption, and this is one on his list (see  for the quest).
