Evidence of the origin of the Ents can be found in the Valaquenta, in an exchange between Yavanna (a queen of the Valar, "...lover of all things that grow in the earth.") and Manwë ("...the first of all Kings: lord of the realm of Arda."), after Yavanna's spouse Aulë secretly endeavors to create the Dwarves. Aulë reminds her that the children of Ilúvatar (Elves, men and now Dwarves) will exploit her creations for their own benefit, "though not without respect and gratitude." The defenselessness of her realm moves Yavanna to plead with Manwë: "My heart is anxious, thinking of the days to come. All my works are dear to me... Shall nothing that I have devised be free from the dominion of others?” Manwë responds by asking, of all she holds dear, what she would have preserved against exploitation, and she answers: "...the Kelvar can flee or defend themselves, whereas the olvar that grow cannot. And among these I hold trees dear... Would that the trees might speak on behalf of all things that have roots, and punish those that wrong them!” Manwë, while deliberating, is overcome by a vision of the music of the Ainur, and grants her request: "Behold! When the Children awake, then the thought of Yavanna will awake also, and it will summon spirits from afar, and they will go among the kelvar and the olvar, and some will dwell therein, and be held in reverence, and their just anger shall be feared." Yavanna returns to her spouse Aulë and reports: "Eru is bountiful. Now let thy children beware! For there shall walk a power in the forests whose wrath they will arouse at their peril." He responds ominously: "Nonetheless they will have need of wood."
