I'm not quite sure what race yet, but he'll be about 21-years-old and utilize both magic and combat skills, neither full mage nor full melee-fighter. When he begins a fight, he will use magic to buff himself and deal ranged magic damage to his enemies. When they get up close, he'll equip his two shortswords and go berserk.
All of the specifics depend on how the races look and what their bonuses are and also on the different spells available. From what it seems now, Destruction will be more than just the repetitive fireball/shockbolt/frostbolt spells it was in Oblivion and Morrowind, which
really makes me happy. I only hope the other schools of magic are similarly revamped.
