Angelos Conquirere
The Angel of Conquest, or Conquering Angel, symbolises the fight against evil, here with the bones of a slain beast, possibly a dragon. She rests, having just vented Wrath.
The sword is symbolic,and whilst used in battle, is only part of her arsenal of abilities and martial arts, some of which could be termed as magical, hence the eradicated flesh and muscle of the severed head, which is but scorched bone now that the dark anima has been cast out and vanquished.
