§ Of the Maiar The Silmarillion

Chief among the Maiar of Valinor whose names are remembered in the histories of the Elder Days are Ilmarë, the handmaid of Varda, and Eönwë, the banner-bearer and herald of Manwë, whose might in arms is surpassed by none in Arda. But of all the Maiar Ossë and Uinen are best known to the Children of Ilúvatar.
