Who is Norhala in 'The Metal Monster'?

Norhala is a mysterious and powerful woman in 'The Metal Monster'[1]. She identifies herself by name, stating, 'I am Norhala'[1]. She is described as having an unearthly beauty, with 'great, wide eyes whose clear depths were like pools of living star fires'[1], skin 'white as milk of pearls'[1], and 'cloudy, METALLIC' hair like 'spun silk of ruddy copper'[1]. Her voice is 'elfin distant, chimingly sweet'[1] and she speaks 'purest, most ancient Persian'[1].

Norhala is not entirely human, possessing 'something stronger than humanness'[1], and can command the 'metal things' and summon lightnings[1]. She is the daughter of another Norhala and Rustum, and kin to 'Him Who Rules!' (the Metal Emperor)[1]. She seeks vengeance against Cherkis for the torture and slaying of her parents[1].
