The principal Fomorians are described as kings. Elatha was son of Nét, described by Cormac as "a battle god of the heathen Gael," i.e. he is one of the Tuatha Dé Danann, and has as wives two war-goddesses, Badb and Nemaind.[187] Thus he resembles the Fomorian Tethra whose wife is a _badb_ or "battle-crow," preying on the slain.[188] Elatha's name, connected with words meaning "knowledge," suggests that he was an aboriginal culture-god.[189] In the genealogies, Fomorians and Tuatha Dé Danann are inextricably mingled. Bres's temporary position as king of the Tuatha Déa may reflect some myth of the occasional supremacy of the powers of blight. Want and niggardliness characterise his reign, and after his defeat a better state of things prevails. Bres's consort was Brigit, and their son Ruadan, sent to spy on the Tuatha Dé Danann, was slain. His mother's wailing for him was the first mourning wail ever heard in Erin.[190] Another god, Indech, was son of Déa Domnu, a Fomorian goddess of the deep, i.e. of the underworld and probably also of fertility, who may hold a position among the Fomorians similar to that of Danu among the Tuatha Dé Danann. Indech was slain by Ogma, who himself died of wounds received from his adversary. Balor had a consort Cethlenn, whose venom killed Dagda. His one eye had become evil by contact with the poisonous fumes of a concoction which his father's Druids were preparing. The eyelid required four men to raise it, when his evil eye destroyed all on whom its glance fell. In this way Balor would have slain Lug at Mag-tured, but the god at once struck the eye with a sling-stone and slew him.[191] Balor, like the Greek Medusa, is perhaps a personification of the evil eye, so much feared by the Celts. Healthful influences and magical charms avert it; hence Lug, a beneficent god, destroys Balor's maleficence.
