Fallen Angel- SDS OC

I do not own SDS or the images used.

The holy war was a terrible time for all the races of Britannia. To combat the demons, archangels were sent to the earth to fight. The greatest of these angel were Mael (my-el) and Alicost (Alli-caust).
But after refusing to complete a mission she is cast out from the goddess race.

3000 years later Alicost reappears do make up for her past betrayals, but whose side is she really on?
