The Elder Things can withstand the pressures of the deepest ocean, interstellar travel, and can hibernate for vast epochs of time. Few die except by accident or violence. Nonetheless, they are made of normal, worldly matter.
Their society is alien, and their motivations are unfathomable to humans. However, a human scientist once claimed they are fellow scientists, not monsters. Their primary achievement is the creation of a servitor race, the shoggoths, upon which they become increasingly dependent. Successive wars with the Great Race of Yith, the Star-spawn of Cthulhu, the Mi-go, and a rebellion of the Shoggoths weakened them.
