The story is a well made mix of fantasy and science-fiction, meaning ,although there's everything from sword and magic to flying fortresses and intelligent battle robots, it's still believeble. Themes of this anime are the questions if one person may be sacrificed to save many and later if humanity is doomed to extinction if let alone. Since these questions may be argued about, the sides in this anime are at no time black or white, but have understandable reasons for their actions. The story is all in all original, but parts of it ( humanity is in a invisible prison set in the past and guarded by intelligent machines) is stolen from "the matrix". thus a 9/10.

most of the important charaters develop as the plot continues. be it from obedience to acting according to own beliefs, from cold rationality to sympathy or from rejectance to trust: Through the characters' changes the story stays unpredictable, which ensures the suspense. Defeated enemies may even become friends, which however, judging by dragonball or bleach, seems to be standard in anime and is more or less expected.

This anime has an opening and even an ending theme! and both sound good.

This anime also has moving pictures, which look very good.

summary stolen from wikipedia: The story takes place in a fantasy world and revolves around a 15-year-old girl Pacifica Casull who is a girl child born in a set of twins into the royal family of the kingdom Leinwan and then abandoned. The 5111th Grendel Prophecy predicts that she is the "poison that will destroy the world" before the sun sets on her sixteenth birthday. As a consequence, she is dropped off a cliff as an infant. Believed to be dead, no one realizes her continued existence until after Pacifica is already 15 years old. Pacifica is rescued by a court wizard and adopted by the commoner Casull family. Her foster siblings - Shannon, loner swordsman, and Raquel, motherly magician - became her protectors. Both siblings are extremely powerful, and more often than not they easily break out of whatever difficult situation they face. Her siblings travel with her throughout most of the story, protecting her from the numerous attempts on her life by people who fear the outcome of the prophecy, should she survive. Both siblings' skills see constant use. By contrast, Pacifica is a mostly typical fifteen-year-old, and her inability to defend herself is a recurring source of self-doubt for her. As the series progresses, the truth about the prophecy slowly comes to light, and even as the more of the truth is revealed, more questions arise. Pacifica must discover her hidden destiny, even as powerful beings that are not human who are supposedly the gods of this world - continuously fight against each other, over her fate, seeking to either protect or destroy her. It turns out that Pacifica is not in fact "a poison who will destroy the world" in that sense...but in fact mankind's last hope, and all part of a plan. A plan that was set in motion a long, long time ago by not primitive humans but highly intelligent and advanced ones, at that. Can destiny be written beforehand? The answer lies deep in the past, five thousand years ago during the Genesis Wars...
