The Elder Things came to Earth from other planets in outer space. The site of their first settlements was in what later became Antarctica - though this was before the breakup of Pangea, and at the time these lands were lush and tropical. Antarctica always remained the heart of their civilization, considered almost sacred, but in time the Elder Things colonized the entire world, first under the seas but eventually spreading to land. During this first undersea colonization they used energy weapons to fight "nameless adversaries". While the Elder Things were always more comfortable under water, after the oceans were fully settled there was a long shift to building cities on land, until their civilization flourished across the entire planet.
