Mu

Mu is a sunken continent that may have existed in the South Pacific between twenty thousand and twelve thousand years ago. It was inhabited by the lloigor, Ghatanothoa, and the lloigor's human slaves.

The lloigor and the humans were the two primary races that lived on Mu. The lloigor, who are invisible "vortexes of energy" fed off of the humans to survive. They also can draw huge amounts of energy for explosions of destruction, and this is what caused the destruction of Mu.

The human population of Mu is thought to live on in the Welsh people.
