Caleb has an oddly baby-ish face, in a bland way, but it's a pockmarked record of war. He's pale, with very light, very dull brown hair that's a rough inch-long fuzz. His eyes are also very pale and dull.
There is something unhealthy-looking about his face, though he looks only about 25 or 30 and his body is strong and vital.
He rarely washes and his skin and hair and clothes are often soiled with old sweat.
His clothes are always extremely comfortable and all-white. Somehow they stay all white even after a particularly horrible rampage - you can see him leave a room, hear screams, and he'll come back in with red hands but clean everything else.
Cal considers himself a god.
It's not really his fault - from childhood he's been treated as one. Somehow he inspires extreme loyalty among his subjects as their emperor, despite being almost completely made up of flaws. He's narcissistic, selfish, sadistic, and, though he isn't completely devoid of intelligence, he often chooses not to use it. It seems they delude themselves in an almost 1984 double think kind of way.
He doesn't go by any title - by now his very name is a title, anyway.
Caleb is extremely cruel to those who serve him, hurting them horribly just for fun. but, always, always, their "noble", "kind" leader comes out of it looking pure and clean, but with the subtle flash every now and then of blood-drenshed palms.
He has no weapons himself - he does not fight, but has an array of bodyguards and soldiers at all times.
Flexible - except that he's always lived as the supreme ruler of a once-great empire, now large and prosperous but beginning to atrophy.
