The Vision of Serge Gamond

I was stood atop the city wall, south of Profetta. I saw an army approaching - several hundred men at least. Clad in glistening white armour, the marched up the road from Rosiloff. At their head was a woman - some 8 feet tall, blond, and with skin so white it appeared to glow. She was wearing a long flowing cape made from white feathers, and carried a golden spear. At her side was a man, grey hair and a dark beard, clad in golden armour and carrying a long curved sword.
The army marched up to the gate without breaking step. The gates were closed, and a shout went out from the wall. "Where have you come from? What do you want?" The man cried out. "We are the holy warriors. We come to your city to destroy an evil which treatens our lands. Open the gates and stand aside." "What is this evil of which you speak?" the guard cried out, but no answer came.
A long pause followed, broken by the sound of a single bow shot. An arrow soared across the sky, and plummeted directly towards the pair at the head of the column. The lady took a step forward, and held up her hand. A beam of light shot out from it, seemingly burning the arrow in mid air, and the light progressed onwards, arcing back across the sky from whence the arrow came. The silence was broken by the screams of the guard burning.
She took another step forwards, and pointed her spear towards the city gates. A great cone of light emerged from it, and the walls, gates and everyone on them was bathed in bright white light, blinding my vision. When the light faded, all that remained was the scorched bare earth. No rubble, no flame, no bodies.
The army marched onwards, in through the gates, and directly to Profetta Torre. The men set fires in the forest, killing any who attempted to flee. They surrounded the fence, and then with a word from the lady, flew over the boundary as if on wings, and then proceeded to massacre our people. We are not fighters, and although we tried to protect ourselves as best we could it was not long until the Torre fell quiet.
My vision shifted, and I saw myself, along with Claudine and Yves, hiding in the chambers below. The only sound was the water flowing through the pipes. Suddenly it began to bubble, and then boil. As we looked at one another, a shaft of searing light punched through from the ceiling. Another, and then another, this one landing straight on Claudine's head. There was barely a moment to hear her screm before the whole tower erupted in light.
When my vision returned, nothing remained of Profetta. The forest around was ablaze, surrounding the scorched bare earth where Profetta once stood. I heard the sound of a thousand boots marching again, and watched as they marched back down the road, as precise and emotionless as they had arrived.
