Ethereal Void

The Ethereal Void, also known as the Vortex, is an all-encompassing celestial framework within which the cosmos is bound.

Description
It has been a major presence throughout the Ultima series, enveloping its many worlds and dimensions and drawing vast power from the life-forces of each. Superficially, it is perhaps best described as resembling outer space, yet entirely habitable to forms of life. A higher plane of existence, the Void cannot be reached by physical travel; it is permeated by magic and accessible only by such means. Nevertheless, a number of beings, objects and artificial constructs find their places in this astral domain.

History
The Ethereal Void was first encountered in  Ultima IV, by way of the the Shrine of Spirituality. Similar instances followed in  Ultima V and  Ultima VI, with the Void taking on its familiar appearance in the latter title and finding itself host to the Codex of Ultimate Wisdom at the conclusion. In  Ultima Underworld II, a vastly different form of the Void was traversed, consisting of blue, orange, red, yellow and purple zones. Arguably, its most significant appearance came in  Ultima VII Part Two, wherein it formed a substantial portion of the lore and, upon the restoration of Balance to Serpent Isle, served as the stage for the Guardian's abduction of the Avatar to the world of Pagan.

Following this event, the Ethereal Void featured in  Ultima VIII as a hub to access the respective domains of the four Elemental Titans, all of whom the Avatar had to defeat.

In Ultima IX, the Avatar returned to the Void to restore the desecrated Shrine of Spirituality.
