Darian and his brother Damion were born as princes of their homeworld, although their parents didn't care much for Damion and treated Darian like the only heir. He lived a pretty nice and easy life early on, but during his childhood their kingdom was invaded and Damion and he fled their world to go into hiding, since their parents were all too willing to let the invaders take Darian if it meant they'd stop the invasion.
Right now Darian's just a sort-of-regular student, but it's obvious he's pretty dang arrogant since his kind in general hold themselves above mortal races AND he's also royalty. I mean, he knows how to put his priorities straight and is pretty down to earth, but he can still be pretty jerky about it and knows he's better than pretty much everyone around him. He just won't say it out loud since he's sure it's heavily implied enough. XP He kind of plays up how much of an arrogant jerk he can be though, so not all of it is completely genuine and is mostly him being sarcastic about it.
