Unit 1016, 'Commander of Ulm', for Late Era Ulm -- description says "The commanders of Ulm are clad in thick armor made from the Blacksteel of Ulm...", forging of which has been forgotten (and the commander has an ordinary Plate Cuirass, not Blacksteel).

Unit 739, Black Acolyte, should probably have a slightly different description from Black Priests; they don't yet know any magic, nor do they yet get an inquisitor bonus.
