Three creatures filled the screen. They looked at each other, and the middle one started to speak again. "We are the Sky Riders," it said in perfect, unaccented Galactic Standard. "We come seeking a deal. We want only one thing. We want the Time Lord. We want the Doctor."

"And what do we get in return?"

The lead creature leant closer to the screen. "Your planet will be spared."

"How you can be ignorant of what planet you're on, I don't know, but I suppose I better tell you. This is the planet Messaline, a human-hath colony."

"Great job," Brittany hissed, as the Doctor lead her towards a stairwell. "You've just landed us in the middle of a war."

."They're coming!" the newcomer shouted, catching everyone's attention. "The Tigers are coming!"

"Tigers?" Brittany whispered to the Doctor, who only shrugged in response.

As soon as the man had shouted his warning, everyone in the room had leapt to their feet, personal belongings in their hands. There was a frenzied dash for the door, and before the Doctor had a chance to ask what was going on, the room was empty.

"I wonder what's gotten into them?" Brittany said, staring around at the vacant chairs.

The Doctor frowned, genuine concern in his expression. "I wonder indeed."

The Doctor stood up, and started to pace backwards and forwards, hands deep inside his trouser pockets. "This war doesn't feel right. It's like someone is messing with time, moulding it like plasticine."

The Doctor quickly judged the distance between them and the soldiers, and was satisfied that they could make it.

"Okay," he whispered. "RUN!!"

The Doctor and Brittany will return in Sky Riders for some more world saving adventure. Tune in next time to find out what is going to happen! The tension is unbearable!
