Become brother of the huge nerd, who is a huge-er nerd
Just because you always like to dress up like your favorite videogame character doesn't make you a huge nerd! (yes it does)

You are Cody Johnsson, brother of Ethan Johnsson.

Your interests are videogames, like Legend of Zelda and League of Legends, and you dabble in book reading and black magics, you know, average college student stuff.

Unlike your brother, you are not an aspiring musician. You used to play piano, and still do whenever you go back home during breaks.

Examine "black magics"
Oh, you know, it's just the normal stuff: fireballs, lightning, ice shards, water control, but your favorite spell by FAR has to be your Cody PAWNCH (definitely not related at all to the "Falcon Punch" at all, nope)

Examine relationship with brother
You have an ok relationship with your borther. When you come back from breaks, you tend to just stay out of each other's way, unless you are playing League of Legends together. Your brother goes to the same high school you did, and all of your teachers loved you. you were an exemplary student, got great grades, and had a great social life. Your borther, however, is much more introverted around most people, and doesn't get nearly as good grades, because his "give-a-fuck-ometer" is running on empty. It must have been tough for him, though. Having to go through high school in your shadow...

Examine Room
Right now, you are living in a pretty crappy college dorm room. two beds, one for you, the other for your roommate, who you don't really see much of, two desks, and some clothes on the floor.

Examine powers
As the Mage of Time, your pretty much a prophet. You can not only see ( and by see, you mean get a very vague and basic idea, can't make this too easy) the future of your own timeline, you can also see (see previous parenthetical note) the past, present, and future of other timelines.
