<P> Compare this with Tolkien's more thorough explanation of the existence of Dwarf - women, given in the Appendix . Dwarf - women seldom leave their underground cities, and are not encountered as frontline soldiers in war, but that does not mean they do not exist . </P> <P> It is said in The Silmarillion: </P> <P> "But of those unhappy ones who were ensnared by Melkor little is known of a certainty . For who of the living has descended into the pits of Utumno, or has explored the darkness of the counsels of Melkor? Yet this is held true by the wise of Eressëa, that all those of the Quendi who came into the hands of Melkor, ere Utumno was broken, were put there in prison, and by slow arts of cruelty were corrupted and enslaved; and thus did Melkor breed the hideous race of the Orcs in envy and mockery of the Elves, of whom they were afterwards the bitterest foes ." </P> <P> This text refers to the Quendi who ran and hid at the sight of Oromë when he came to lead them from Cuiviénen westward . These "corrupted elves" were the first orcs . There are various races of orcs (though with later races of orcs came different physical and non-physical characteristics like increasing tolerance to sunlight) all identical in their hate for everything that Ilúvatar and the Valar had constructed (including themselves) to resemble the hate that lay within Melkor . </P>

Lord of the rings how do they make orcs
