Aside from Oromë, Ulmo (Q."Pourer") was the best known of the Valar, for his Spirit dwelt closest to Middle-earth. Ulmo's essence swirls through each rain, courses through every stream, and lies in every pool and bay in Arda; he comes with each morning's dew. Ulmo resides in the highest snows and the deepest springs. As water is the "blood" of the World, the Pourer is truly the Spirit of the Veins of the Earth.
Ulmo rarely took a fána, for he seldom came to land. Instead, he prefered to shift with his capricious waters. When he rose in form, though, he typically appeared as a huge manifestation of the themes of the sea. His indigo eyes peered from beneath a chain hood and shining mad, a coat of ever-washed fish-scale armor whose color was of glittering blue and silver, upon a robe and skirt of shimmering greens.His skin and beard were blueish-silvern in color,his beard occasionally seeming to be nothing more than tangled seaweed. His was a form with the elusive qualities that befitted his nature.On and off he also appeared in the shape of a withered old Mariner who wandered the shores of sole Islands within the Belegaer.
Ulmo is second among the Vala Kings and third in the hierarchy of the Exalted Powers. Only Manwë and Varda stand above him in Eä's scheme. A loner who rarely takes form and only occasion- ady visits Valinor, he is the virtuady autonomous master of the deeps. Ulmo sees and hears ad that transpires beneath the waves and knows every- thing that occurrs where water flows. His knowl- edge of the Middle-Land oft times exceeds even that of Manwë and Varda, for things and events which cannot elude the Ocean Lord's notice can be hidden from the King and Queen. Ulmo's unique dominion threatened Morgoth from the very Beginning, since the Black Enemy's claim as King of the World did not extend into the sea. Morgoth hated water and feared the untameable ocean, so he attempted to supplant Ulmo by offering the Sea-lord's vassal Ossë the Kingdom of Water. Ultimately, Ossë tepudiated the Black Enemy's advances and, with the inter- cession of the Maia Uinen (Ossë's spouse), he was pardoned by his lord. Ulmo's voice is as deep as the sea. It is the greatest in Eä, and his servants are the finest singers ever to grace Arda, save the Vala Vana. Eru conferred more music upon Ulmo than he gave the other Valar, and his command of song- lore remains unparadeled. It was his people who taught the Teleri how to sing. Ulmo also directed Ossë to instruct the Teleri about shipmaking, and these skills were evident in the wondrous creations of the great Sinda Cirdan the Shipwright. This precious tutelage, combined with Ulmo's mastery of their beloved sea, led the Teler Elves to acknowledge Ulmo as their patron (alongside Varda). Ulmo's concern about the welfare of Eru's Children extended beyond the Teleri. The Ocean Lord transported many of the Eldar to Aman and counseled the Free Peoples throughout the struggles during the War of the Great Jewels at the end of the First Age. Knowing of the secret places where water ran, Ulmo revealed the hidden caves that provided the Noldor refuge in the later stages of the resistance against Morgoth. As a result, many of the High-elves count the Lord of Watet as a friend—despite the toll Ulmo exacted during the Flight of the Noldor. (The Pourer's blistering snows, pounding rains, and roaring seas claimed many lives and sowed considerable fear during the bittersweet Noldo migration.)
