Fighters are boring. You get your sword, shield, and that's it. All the way to ToB. They don't have any other skills except fighting, get no spells, and by the time you get past 10th level, all you get is three hit points per three hundred thousand experience points. Dull. Very dull.
I suggest a thief, later dualed to a mage. Pick pockets, hide in shadows, move silently, set traps, open locks, find/remove traps, detect illusion, backstab, plus a whole arsenal of spells.... need I say more?
