"Alright, Guardian. The time has come. I must tell you more about our dark responsibility. The Professors and I may not look like it, but we are all many thousands of years old. Many millennia ago, Medivh pursued me, trying to kill me. He was so mad with power, he felt he should kill anyone who could use magic... to ensure he had no rivals. Eventually, I found Fumbledoor, Sneverus, and the others, and we combined our powers to defeat Medivh... but we could not completely kill him. He is so powerful, he can re-animate himself back from the dead each time he is killed. So, we decided to build the College, which allows us to focus our energy, and keep Medivh sealed away below us. Guardian, I want you to speak with Desna, at the Focusing Point behind the college. She will tell you more."
