Giant

Giants, sometimes referred to as Worldwalkers, are a nomadic people of extraordinary size and longevity. Unlike the smaller humanoid races, giants have the strength to survive beyond the walls of the Citadels, migrating in huge caravans ranging in size from dozens to hundreds of giants. Like the other humanoids, though, all the giant gods died in the World Death. The giants were very close to their gods, and have suffered greatly in their absence.
Giant souls are usually very strong and noble, so dulleyes symptoms are particularly strong in giant children after a couple generations have now passed since the World Death. Most caravans have established long multi-year layovers in citadels to birth and raise their children, or secluded themselves to hidden ancient fortresses. While this puts a strain on citadel resources, the giants' services are essential in maintaining and repairing damaged sections of the rail network.
