The TARDIS cloister bell sounded as The Doctor looked around. His eyes were wide and he was moving slowly. Derpy opened her mout to speak but The Doctor held up a hoof to stop her. The green lights of the TARDIS had gone off and Derpy and The Doctor now stood in almost complete darkness. The Doctor turned to look at the scanner. He frowned as he looked.
"What is it?" Derpy asked, worried. The Doctor didn't answer. He swallowed and turned to her.
"I think we should go." He said "We should really... go." He ran past her and out of the door. Derpy smiled at how The Doctor always wanted to explore. She followed.

The Doctor was standing with his eyes wide staring at the planet they had landed on. Red grass formed a field underneath the burnt orange sky. Two suns shone in the sky.
"Impossible." The Doctor seemed worried.
"What is it?" Derpy asked.
"Do you remember I told you about Gallopfrey?" Derpy nodded slowly. She realised what he was telling her.
"Wait..." She said "Then how are we here?" The Doctor just shook his head.
"No idea. But since we're here we might as well look around." They both trotted across the pastures of red grass towards a towering citadel.

They walked through the halls towards two huge doors. The Doctor pushed them open with his hoof and went inside. There was a huge table in the middle of the small room. All of the ponies around the table turned round.
"I have something to tell you." The Doctor said to the one at the nearest end of the table.
"And what is that,Doctor?" They replied.
"You better be careful what you do here. Because as long as I'm here you can't get away with anything." The pony glared at him and a cage suddenly dropped down from the ceiling, trapping Derpy and The Doctor. They looked around the cage.
"You know, Rassilon." The Doctor said "After a billion years I would expect you to come up with better traps than this." Fire suddenly sprung up around the cage. Rassilon smiled.
"You should be careful what you say." He said.
"And you should be careful what you put in this cage." The Doctor replied.
