When the exiles were driven from the Realm Below, it was Soranath who made them weapons. Clan Soranath is one of the smallest clans, but its influence reflects the talents of its artisans. Other clans have mines and fields—it’s Soranath who takes what they produce and makes wonders.
Not all artisans are from Soranath, just as not all of the denizens of Soranathhold are artisans. Most blades in Mroranonhold are forged by Mroranon smiths. But Soranath artisans are unmatched in their techniques and their work ethic. Rather than being bound by secrets of the past, Soranath smiths are always looking for ways to improve their techniques, searching for new sources of inspiration. While this sounds impressive, Soranath is a small hold with limited resources, without the capabilities either in research or production of House Cannith or the Arcane Congress. The artisans of Clan Soranath won’t change the world with their works, but they produce remarkable things for those who can afford it.
Soranathhold is small, with only three spires. Its families are tightly knit, and the divide between tenant and clan is a thin line. Industry is the prime virtue of Soranath, and its people work hard and live austere lives; for Soranath dwarves, a job done well is more satisfying than any luxury. Soranath has abundant deposits of dragonshard geodes, and thus isn’t dependent on Tharashk, but doesn’t seek to challenge Tharashk as an exporter of shards. Due to its otherwise limited resources, Soranath is dependent on other clans for many things, including protection. Soranath artificers are fascinated by the potential of the Realm Below and what they could learn both from the Udar artifacts and the symbionts of the daelkyr, and Grayroot Spire has been experimenting with fleshcrafting. However, they are artisans, not warriors; they must hire others to venture into Sol Udar on their behalf.
The Soranath dwarves are devoted to the Sovereign Host, especially to Onatar; they are quick to assign credit for any great work to the Sovereign of Fire and Forge. There may also be a cult of the Traveler within Soranath, perhaps in Grayroot Spire; if so, it keeps its true devotion well hidden.
Soranath dwarves are generally guild artisans, acolytes, or sages. Artificers (primarily Battle Smiths) and clerics of the Forge are both logical classes for Soranath dwarves.

Soranath possesses excellent crafters, who work with other clans to produce finished goods from their raw materials. As such, they are friend to all, though the other clans resent being unable to match Soranath’s skill. Sor, the clan’s founder, quarreled with Mror in ancient times, and their clans continue the feud today.

During the Last War, Soranath was closest with Thrane and Valenar.
