Came here right after the Fall of Atlantis.

I used to call them the "Egyptian reinforcements". However most of them ended up as the Indian pantheon, a few others in North America.

They were looking for helium (sounds better than "gold to fix the atmosphere" wink wink). Quickly descended into cannibalism. Then ruled over by other aliens and Earthlings. Tried to destroy each other telepathically as mercenaries. Fascinating though an attempt to cross the Pacific by the builders of Teohtihuacan ca. 500 BC. Fitting for Columubes Day.
