The Master was originally known as Koschei when he grew up on Gallifrey in the House of Oakdown. The Master and the Doctor shared the same heritage and upbringing. Despite his childhood being more a life of duty, he had a friendship with the First Doctor. The two youths would play in the fields near Koschei's home which was his father's estates, with pastures of red grass near Mount Perdition. They used to sneak out of the Capitol and drink with the Shobogans. On one of these outings, Koschei picked a fight with six drunken Shobogans.
