Skyrise

Skyrise is a Phoenix that has come to the Serpent Isle to counter the imbalance. She appears in Ultima VII Part Two.

Description
It is unknown how exactly Skyrise died. The Avatar found her body on the northernmost of the Isles of the Mad Mage in some ruins. Pulling a lever to cause the lava to engulf the body, Skyrise was reborn.

She was surprised that the Avatar asked for her real name, as she'd mostly just been addressed as "phoenix." She then went on to tell the Avatar about her people and how they were drawn to places where the balance had been disturbed. She continued, that with her now alive, balance could be restored to Serpent Isle.

In thanks, she then gave the Avatar one of her eggs, which was exactly what the hero needed for Erstam to exchange it for his Serpent Jawbone.

Trivia

 * It is possible to shoot Skyrise with arrows and kill her. However, she's reincarnated at once and complains to the Avatar to stop this foolishness.
 * According to early design documents for Serpent Isle, a lit torch would have been needed to be placed on the nest to rise Skyrise from the ashes instead of a lever.
