Elden Ring boasts a rich tapestry of NPC questlines, significantly enriching the game's lore and even unlocking otherwise inaccessible areas. FromSoftware's signature cryptic storytelling, however, makes initiating these quests challenging, as there are no map markers or quest logs. This guide provides a concise overview of nearly 30 intertwined NPC quests, with links to comprehensive walkthroughs for each.
