Smithy (Norsca) is a Norsca military support building in Total War: Warhammer. Smiths are usually thralls, stolen from the south and kept alive for their skills, with access to a very basic smithy.
Background
A smithy is a crude workshop and forge, usually constructed by a smith from outside the tribe, a slave taken from the southlands and only kept alive due to his useful skills. In the most basic of surroundings, he is forced to beat and shape armour fragments and shoe the Marauders' vicious steeds.
