Andromeda is an demon in the series.
In Greek mythology, the princess Andromeda is the daughter of the king of Aethiopia, Cepheus, and his wife Cassiopeia. When Cassiopeia arrogantly boasts that she is more beautiful than the Nereids, Poseidon sends the sea monster Cetus to ravage the coast of Aethiopia as divine punishment due to her mother's arrogance. In desperation, King Cepheus consults the oracle of Ammon, who announces that no respite can be found until the king sacrifices his daughter, Andromeda, to the monster. Andromeda is then chained to a rock as a sacrifice to sate the monster, but is saved from death by Perseus, who marries her and takes her to Greece to reign as his queen.
Andromeda is one of the 48 constellations listed by the 2nd-century Greco-Roman astronomer Ptolemy and remains one of the 88 modern constellations. Andromeda is most prominent during autumn evenings in the Northern Hemisphere, along with several other constellations named for characters in the Perseus myth. The Andromeda Galaxy is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest major galaxy to the Milky Way.
Andromeda may alternatively be named after The Andromeda Strain from the novel and movie adaptation of the same name, in which the titular extraterrestrial virus poses a lethal threat.
