Nessa

A Queen of the Valar (Valier), sister of Oromë and spouse of Tulkas.

. . . she also is lithe and fleetfooted. Deer she loves, and they follow her train whenever she goes in the wild; but she can outrun them, swift as an arrow with the wind in her hair. In dancing she delights, and she dances in Valimar on lawns of never-fading green. --Valaquenta
