The Ghostbloods are a secretive and dangerous organisation that operates not just across Roshar but across multiple worlds in the Cosmere. Led by a figure whose true identity is one of the series' major reveals, the Ghostbloods seek to control the movement of Investiture - magical energy - between worlds, giving them power on a cosmic scale. On Roshar, they pursue Shallan Davar as a potential agent, drawing her into a web of espionage, murder, and competing loyalties. The organisation is ruthless and pragmatic, willing to kill, manipulate, and betray to achieve its goals. Their activities intersect with nearly every major faction in The Stormlight Archive, and their true ambitions extend far beyond any single world.
