Very nice.
Two powerfull wizards start an epic duel. one rises skeletons and zombies from the ground and the other one calls the power of the sun to destroy them. Then, the evil wizard dispears. The holly wizard doesn't know where he is and so the evil one appears behind him with a venomous dagger and stabs him in the back. The white wizard has powerful healing magic but the poison is still stirring in his veins. Just before dying he has time to cast the sacrificia luminarea spell, wich kills him but makes him explode like a bomb of immense light energy and by that the evil wizard gets torn apart.
Thats what I felt from this music =3
The rest of the story I feel from your song will be in another review of another of your songs, where the evil wizard, who was very powerful, defies satan himself, to gain control of hell. While the white mage, seeks help from the almighty god.
