Your father is a god named Talos, also known as Tiber Septim, Ysmir, Dragonborn, and the heir to the Seat of Sundered Kings, is the most important hero-god of Mankind.

Much of his life as the mortal Tiber Septim is shrouded in legend and hearsay, but one feat is undisputed: he became the first person to successfully unite all of the nations of Tamriel under a single Empire. Talos is worshipped as the protector and patron of just rulership and civil society, and his Nordic aspect of Ysmir is also seen as the patron of questing heroes.

Your dad left you to live on earth, but he's watching you all the time. And if he is on earth, he will be very big, he can control his growth in any way
