After poking into various sources, Majestic Hero was finally able to determine that, through his informant Squealing Hog, the Demon Faction was indeed trying to complete the Golden Keys Quests. Their version of the Golden Keys Quests was to complete ten quests from Demigod Underearth Elder through Mobile Chambers and only the ones who acquired the keys were given access to the Buried City. This appeared to resemble the quests on the Eternal Peaks a lot, except that their versions required them to receive the quests underground. However, there was one thing that concerned everyone.
The second quest for the Demon Faction was also the "Revenge Quests"—quests that required them to kill ten Dark Knight Commanders from ten different areas that were under the purview of the ten Mobile Chambers.
Therefore, the ten Dark Knight Commanders were also the Demon Faction players' targets.
