Elder World

The Elder World refers to the ancient world as it existed long before the Thurian Age and the Hyborian Age. During this elder age, humanity was in its infancy and the earth was dominated by all manner of strange creatures and nightmarish monsters, including the Serpent-Men. The Elder World came to an end when human beings conquered these monstrous foes, destroying them or driving them back into the wild, remote places of the earth. It has also been referred to as the Elder Planet and the Elder Universe.

When Conan first met the elephant-headed Yag-kosha, he thought he was "face to face with a demon of the Elder World".
