Restless Ghosts is one of many obscure side quests you'll pick up while exploring Ashenfall in Runescape: Dragonwilds, specifically, when you visit the Crumbling Well in Bramblemead. When you're nearby, you'll be able to interact with the well by pressing E, which lets you retrieve the mysterious Ghostspeak Amulet, and immediately begins the quest.
Annoyingly, though, you aren't given much explanation as to what you're supposed to do with it. If you open your map to check the quest, it just says "search for a purpose for the Amulet of Ghostspeak."What this really means is that you'll need to track down some ghosts which can only be found at night.
