Breath of Air

The Breath of Air is one of five artifacts which were created when the great Blackrock Obelisk of Pagan shattered. It appears in  Ultima VIII and is affiliated with the Titan Stratos.

Description
During the apparent conflict between the Titans and the "Destroyer," the Great Temple of Pagan was destroyed and the ceremonial blackrock obelisk within it sundered into five portions. One of these fragments fell to the lands of Argentrock Isle and became known as the "Breath of Air," as it was used as a source of power by the Titan Statos.

The Breath of Air held portion of Stratos' power, as it had been a part of the sacred column which had allowed the Pagans to summon her and her brethren into existence. Using it, the Titan could share her mystic powers with her adherents, enabling the devout to utilize the healing arts of Theurgy.

During their quest to leave Pagan, the Avatar stole the Breath of Air from Stratos, robbing the land of healing magic and severing the flow of energies which kept the ancient Stellos alive. They would later use the artifact against Stratos herself on the Ethereal Plane, destroying her that the hero might steal her powers and rebuild the Obelisk.

Trivia

 * It's possible to render the game unwinnable by using the Breath of Air on Stratos prematurely. Doing so will teleport the Avatar to the Ethereal Void, whether or not the player is prepared for the endgame.
