Skyfall

Ikaros, a young winged girl, and her brother, Gabe, are traumatized when their parents are murdered in an ambush. They are left to fend for themselves at a young age.
12 years after the murder just when they think they're safe Fenris, the only living Cerberus among mankind, confronts them and tells them about a kingdom who wants them dead. As the only living heirs to the Kingdom of Ciracein, they have no choice but to run. Next thing they know they are taken to the Kingdom of Segan by Prince Dominic for safety.
All of a sudden there are kidnappings happening all over the land of Eregor. Including someone close to Ikaros. A kingdom goes bezerk and obtains a special object that can eliminate anyone the owner wants dead.
Ikaros is the only one of her kind with the powers she has which makes her a powerful being in the supernatural world. But she's faced with a horrible decision...
Save the kidnapped people or destroy the object of destruction before it's too late.
