Children of Aulë

Elves and Men were an intrinsic part of Ilúvatar's plan for the World, and so were together referred to as the 'Children of Ilúvatar'. The Dwarves, though, were created independently by the Vala Aulë, and only afterwards given true life by Ilúvatar. So, that race was known in Elvish as the Aulëonnar¹, translated as the 'Children of Aulë'. The Dwarves themselves had their own Dwarvish name for their maker, whom they called Mahal. Aulë also earned another Elvish name for his deed: Návatar¹, which means 'Dwarf-father'.
