Alcyone

アルシオーネ

Alcyone is an ice sorceress who studied under Clef and was raised to serve the Pillar. However, she fell in love with the high priest, Zagato, and became his servant for this love, although the affection is entirely one-sided. In the manga, she is killed after failing Zagato not once but twice. In the anime, she lives on until near the end of the second series; shortly after Zagato and Esmeraude's deaths, she is captured by the evil witch Debonair, who brainwashes her into becoming her slave. Lantis captures Alcyone in battle, but she has lost her memories; when she recovers them, she reveals Debonair's plans for Cephiro and Debonair's location, but her former mistress kills her before she can finish.
In the Sega Saturn game, Alcyone appears to die, then comes back near the end of the game in the later part of Zagato's palace.
Her name is occasionally misromanized as "Alcione"--this was featured in the first run of the English-language manga. Her name comes from the Subaru Alcyone SVX. In the Spanish version of the anime, she is called Alanis.
