Narathun is a small clan, but has always had power. The mythic hero Narathun was the lone wizard of the exiles, and their people hoarded this knowledge. Narathun was renowned for its magewrights, especially its oracles; while they draw rubies and sapphires from their mines and produce beautiful jewelry, secrets have always been one of Narathunhold’s primary exports. Narathun dwarves appreciate tragedy and sacrifices. The clan is known for its artists and its bards; its work is unquestionably beautiful, but certainly more morbid than that of other clans; it’s no accident that its largest city is called Shadowspire.
In the modern age, the dragonmarked houses and traditions of Galifar have brought magewrights to all holds. But its oracles are still respected, and the Ebon Library of Shadowspire is the one of the finest schools of divination in Khorvaire. Narathun sages have always asserted that no knowledge should be forbidden, and Shadowspire holds temples both to the Shadow and to the Blood of Vol. Clan Narathun is fascinated by the Realm Below, though it lacks the forces to push as deeply into Sol Udar as it would like, and Narathun patrons might well employ adventurers willing to risk their lives in the depths. Narathun artificers have embraced the study of fleshcrafting; while they are no match for Mordain the Fleshweaver, they have made remarkable developments over the past few decades.
Narathun dwarves hold long grudges. They have never forgiven Tordannon and Toldorath for thefts that occurred before Bal Dulor, and despise Droranath for a murder that occurred eight centuries ago. Doldarun has long condemned Narathun for its “foul practices,” and its pursuit of fleshcrafting has exacerbated this. However, the other clans value its jewels and its knowledge, and others have always stood in between Narathun and Doldarun. Soldorak and Narathun are staunch allies, reinforced by their interest in the Realm Below. A character from Narathun lends itself more to introspection than interaction and bargaining, and Narathun dwarves are more likely to be artificers or wizards than warlocks. Narathun entertainers and bards produce haunting works; the College of Whispers is an appropriate choice. This is also an excellent clan for hermits, acolytes, or clerics tied to the Dark Six or the Blood of Vol. Despite the propaganda spread by Clan Doldarun, Narathun dwarves are no more likely to be evil than any others.

Narathunhold contains mines of precious gemstones, and Narathun jewelers are among the best in the world. They work with Mroranon to create ceremonial weapons and with Doldarun to create fi ne jewelry. Narathun feuds with Droranath, which it says reneged on a business deal long ago, and with Toldorath and Tordannon, which it believes robbed it in ancient times.

During the Last War, Narathun was closest with Cyre and the Lhazaar Principalities.
