Shadows; part 2

As the wind blew through the graveyard of trees, the tiniest voice could be heard over the clanging of swords. The stubborn pair were being watched. But by who? The girls both simultaneously stopped and were immediately back to back. Slowly they started to turn, swords at the ready, observing all of their surroundings. Minute orbs of light started to dart from the main glowing sphere, and once the small light balls had made a large circle around them the main light was absorbed by darkness. Still seeing nobody, the girls faced each other. They gave each other a slight nod and faster than light they began to run. The light circle travelled with them as they ran. The voice was getting louder and louder but they ignored it. They knew exactly where they were going.

Eventually the dead trees petered into nothing and they were surrounded by openness. The lights vanished, and only the emptiness of the night remained, but they could both see perfectly well. Slowly they started walking, straight ahead, leaving the hollow voice of mystery behind.

Three miles later, the girls were still walking in silence. The outline of a large house could be seen. The girls walked on. Calmly one turned to the other and said “I guess we’ll have to finish this tomorrow.”
“I guess we will.”
“Hopefully we won’t be so rudely interrupted again. By the way, who do you think it was?” she asked slightly accusingly.
“I don’t know, I thought it might have been to do with you”.
