The journal
The personal writings known as the Lost Diary of Walter Emanus detail the experiences of Professor Walter Emanus as he excavated the Temple of Exar Kun. During this time, he fell under the influence of the spirit of Exar Kun, becoming his servant. When a group of spacers launched an assault on the Cult of Exar Kun within the temple's underground passages, they came across the diary's scattered pages.
The 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game created by Sony Online Entertainment and distributed by LucasArts, featured the Lost Diary of Walter Emanus before it ceased operations on December 15, 2011. The "Exar Kun" Heroic Encounter, which was launched with the "Chapter 9" update on April 3, 2008, included the Lost Diary of Walter Emanus. As part of the "Exar Kun" Heroic Encounter quest, various NPCs dropped pages from the journal. Upon collecting and assembling all the pages, players received the complete Diary as a reward.
