This cache is a part of a series of Star Wars themed caches along the High Peak Trail. These caches are designed to be able to be found by cycling, walking, or (horse) riding and are available to most abilities. This cache highlights the ever-hungry Sith lord, Darth Nihilus, Lord of Hunger.
Darth Nihilus was a human male who reigned as a Dark Lord of the Sith during the era of strife following the Jedi Civil War. Before becoming a Sith Lord, he lost everything during the Galactic Republic's war against the Mandalorian Neo-Crusaders. He survived the activation of the Mass Shadow Generator superweapon during the war's final battle at the planet of Malachor V - which surrounded the planet with a destructive spatial phenomenon known as a mass shadow. Experiencing the shadow that obliterated almost everything on and around the planet made Nihilus feel empty whilst craving Force energy, like a hunger. The torment painfully ravaged his body while rendering him a wound in the Force. He was found by a seeker of such wounds: the former Jedi Master - Kreia, who became the Sith Lord Darth Traya and told him that she could teach him to feed his endless hunger. He accepted her offer of apprenticeship at the Trayus Academy on Malachor V, where he, over time, became one of three concurrent Dark Lords of the Sith.
Together, they formed a triumvirate with Darth Traya at its head and her other apprentice, Darth Sion, as the third member. The trio chose individual titles for themselves, Darth Nihilus becoming the Lord of Hunger. The apprentices grew in strength throughout their training and eventually overpowered their Master. Sion defeated Traya, while Nihilus sapped her Force energy. The two Sith then combined power to sever her connection to the Force and sent her into exile. Nihilus' affliction developed to the point where his body began to erode and the Dark Lord was forced to call upon the dark side of the Force to encase his spirit within his mask and armor to stay alive. He and Sion then began the first Jedi purge, causing the virtual extinction of the Jedi Order.
