First time writing one of these but I like the idea. To be honest I don't even know if this is the kind of response you're looking for but this is how the music speaks to me and how my mind thinks about a scene within it. That being said my mind sees it essentially as a two part simultaneous movie style montage (which in turn makes me think of Team America, :) ). Anyway, I'm sure the photo also contributes to the way I placed the music and some of this I would have to say is in part inspired by the movie Thirteenth Warrior. That all being said, this is how I see the scene.
As I said I see it as more of a film shot so this is how the theme and camera appear to me. The effect would be that dark gritty real effect you see now a days (sort of ala Sherlock Holmes) and it would all have a bluish dark hue to it which would contrast starkly with the presence of blood and fire which would be ever so slightly over emphasized. The camera would be constantly in motion swirling around the two main characters from various heights and altitudes capturing the scene from their perspective of the battlefield as well as giving a larger overview at times but always moving in a constant circle at a rather quick pace.
The two main characters are a warring Celtic King and his Queen wife. The scene opens in the midst of a battle. The king stands in the middle of the field. He's bloodied, dirty, and disheveled but still strong. He has long hair braided with leather cords and is bearded the same way. He wears various furs and Celtic attire though has very little armor remaining and he carries an unbelievably large broad sword which he holds at waist height as he peers around. As he turns, the camera turns with him and reveals the battle. Bodies are strewn about in various configurations of death. Men continue to hack at one another. The earth is dark, torn, trampled, and muddy from mixing with blood. The sky is overcast and dark. The battle rages in a clearing and the forest around it is dark and non nondescript giving the impression of a hedge made of dark twisted branches occasionally broken up by the presence of bright orange red yellow pockets of fire. In the distance beyond the forest a large orange yellow flickering and pulsing glow lights the bottoms of the low overcast sky telling the king that his village, and possibly all that he loves in the world, is burning. As the king looks around, an enemy attacker sprints toward him with a raised weapon. The king engages him, struggles with him, then dispatches him and returns to surveying the battle. He seems to be looking for someone. As the camera continues to spin, the king's eyes fall on one man in the battle who finds the king at the same instant and the surrounding battle blurs. They are the only two men left in focus and the king stands his ground as the other man begins a purposeful walk toward him killing the king's men who find themselves in his way.
Here the scene shifts and blurs as the camera continues to spin. When the blur ceases, the scene revealed is now the king's village. The dark bluish overcast is somewhat replaced by a brighter orange overcast as the scene unfolds to reveal the King and Queen's village engulfed in billowing flames. There is no sound save the music but one can almost hear the cracking and splintering of wooden structures as they give way to being consumed and fall in upon themselves. As with the king, the camera now spins about the Queen. She's beautiful and fair with long blonde hair. Her face is streaked with dirt and mud and a small crown remains fixed upon her head but askew. She wears a cream dress that's meant for working and it fits her tight at the top and looser at the bottom to allow her freedom of movement. She carries a smaller sword and small buckler shield. Around her a smaller battle progresses. Men of the king's enemy attack those left behind in the village which consist mainly of women and older men unfit for the greater battle. Children are seen crying and huddling away being protected by the women who have not taken up arms. Some smaller boys and a few of the smaller girls have found various weapons for fighting or buckets of water and attempt to put out blazes. The camera swirls around the Queen as she engages in combat with various men of greater size than her own. Through ferocity, cunning, skill, strength, and in defense of those about her she dispatches the various opponents as they come. At the conclusion of each engagement she looks over the forest towards the direction of the greater battle beyond the forest. Her face is a mixture of exhaustion, worry, fear, sadness, anger, and determination.
Again the scene blurs and returns to the King. He's engaged in ruthless close quarters combat with his enemy, a rival king and the greatest threat to his land and reign. Their contest continues and is evenly matched. Both men are exhausted but in the end the King is able to dispatch his rival as he is strengthened by the furry of seeing his village burning in the distance, his utter disgust with the cowardice of the rival king's attack on the innocents of his home, and in his love, desperation, and hope to end this battle and return to his village to find his wife.
As the King finishes killing the rival, the camera shifts again back to the Queen who is pulling her sword out of a man's stomach. The front of her cream dress is soaked through with his blood and spattered in other places by the blood of others. Around her old men and other women are falling the remaining enemies and some of them are falling in the process. The Queen surveys the destruction of her village and sees countless fires raging uncontrollably, men, women, and children lying dead or wounded in the dirt streets, and horses running wildly and terrified. She sets a course towards the edge of the town staggering somewhat in exhaustion and sadness but continues through sheer will and a queen's determination borne of duty.
The scene cuts back to the King where the battle is almost spent. The rival king's men continue to die or flee from the King's pursuers. Some the king's men continue to fall. Another group of men near the king are gathering and stacking branches into a massive pile. Once complete, one man hands the King a lit torch and the King throws it upon the branches. The branches catch and begin to burn letting off a ten foot thick column of white smoke straight up into the air and it billows and spreads up against the low dark grey cloud deck.
The scene cuts again back to the Queen who in the same instant uses a piece of burning barn as a torch. She throws it into a large brass bowl fifteen feet in diameter and filled with bundles of natural fuel. They catch instantly sending up an enormous white column of smoke. As she steps away from the flame and smoke she looks in the direction of the King and sees the column of smoke indicating the King's victory and telling her that he still lives. The Queen's knees give out and for a moment she steadies herself on the tip of her sword before she collapses to the dirt falling victim to the exhaustion and emotions she had previously banished in order to fulfill her duties. Though no less a queen, she lays in the street weeping tears of sadness for her people overwhelmed only by simultaneous tears of joy for the life of her husband.
The scene cuts back to the king who looks toward the orange glow of his burning village as he locates the signal column of his wife. He falls to his knees facing the village. Love, amazement, and thankfulness mark his face as tears begin to run over and down the mud, smoke, and blood that covers his face. He doesn't weep and his face remains strong, but his tears flow freely like rivers into his beard.

Well that's how that piece of music talk to me. Like I said, I don't know if that was what you were looking for but that's sort of how my mind sees it. Thanks for sharing the challenge.
