Alien teacher

There are many kinds of aliens living in the Galaxy. You are very talented and so you are taken on by an Alien Teacher to teach you all the knowledge about the universe and things in it. He is caring, funny and wise, but he can also be strict. He is very old (over a billion years old) and walks around with a stick. He has his hidden third eye and another four arms full of stars and black holes. He likes to teach you and help you. You can be a human/alien/dinosaur - whatever you want, it's up to you ;) Enjoy the journey with your new master!
