"So, where are we going again?" Rose asked curiously.
"I'm not quite sure," the Doctor answered. "The TARDIS just took over. I have no control over where we land. Let's see where she takes us."
The TARDIS landed with a thud. "We're here," said the Doctor as he walked towards the door. When it opened, a rush of cold air sent a shiver down Rose's spine. Outside, the world was covered with a thin layer of fresh snow, giving the illusion that the land had been lightly sprinkled with powdered sugar. The Doctor smiled at the sight of it and looked back at Rose, his eyes full of excitement. "Let's go!" he urged. Rose grabbed her jacket and walked out into the snow, the Doctor at her side.
The pair looked around to see a few leafless trees, surrounded by a ring of great mountains. The TARDIS seemed to have landed in a meadow in the center of the ring. The only signs of life were the trees. Something didn't seem quite right about that, but The Doctor ignored the feeling. 'Probably just nerves at not knowing where we are' he thought.
Rose spread her arms and spun around once as a few snowflakes began to fall, sprinkling her hair with the white dots. She tilted her face to the sky and closed her eyes, enjoying the fresh air. The Doctor looked at her and smiled. She looked quite pretty with the snow in her hair. She lowered her face again. "Come on. Let's explore," she said cheerily. The Doctor nodded and started to walk towards one of the surrounding mountains. He stumbled over an untied shoelace and stopped to tie it, Rose right behind him.
Suddenly, he heard Rose gasp. The Doctor looked up and saw that she was gone. "Rose!" he called. "Rose!" He saw footprints in the snow leading away from where she had been standing and began to follow them. As he was running along beside the footprints, calling Rose's name, he realized why this place didn't seem right. They were on Virdi, a planet that looked beautiful, but was home to a savage race called the Virdians. They would use their planet's beauty and abundance to lure passing space travelers in, and then capture them to sacrifice to their goddess, Virtia.
The Doctor dodged a tree and kept running. When he looked down at the footprints again, he realized he had lost them! He doubled back, but it seemed that the footprints had just, stopped. The Doctor stopped to Virdians didn't have wings, so if Rose had been captured she couldn't be in the air. They didn't jump or climb either, so she couldn't be in a tree. The only thing the Virdians did other than sacrifice things and the processes necessary for life was burrow, and there weren't any holes in the ground, so where could they have taken her? No other races dared to live on this savage planet, so only the Virdians would have been here to take her.
A deep, booming laugh echoed through the air. "Doctor," a voice said. "We've been expecting you."
