Funny thing about Time Lords. We tend to go to war rather a lot more than people expect. There was this one war, a long,
long time ago. Before I was born. Before Time Lord society as most people think of it came about. My people called those days the Dark Times. The war was waged between two races: the people of Gallifrey, and a people known as the Great Vampires. We won, at a heavy cost. After the war, Rassilon left an order for every Time Lord and Time Lady, down through the generations to the very last of us. Destroy the King Vampire. Something to think about, isn't it?
