Off the top of my head, from the point of view of Marcus.
In the eyes of another.
Octar is a soldier. Solid, dependable, reliable. Marcus has come to depend on Octar, and in fights they often seemed to end up working together. Octar doesn't say a great deal (as Mazanita said) he was content to let others lead. Definately not LE, he strongly resisted killing the witch-maiden, seeing the killing of a woman as a despicable act. His conscience troubled him greatly afterwards, even though it resulted in the 'cave-men' withdrawing back to their homelands.
Brioc is a relucant leader. He leads because the responsibility has been given to him. He listens to others, especially where they know more than him, and will accept their suggestions if they seemed reasonable. Marcus respects Brioc, and follows him willingly. The others seem to as well.
Tullius is a lunatic, always twirling his battleaxes and leaping into any combat with gusto. Marcus thinks he's reckless. But Marcus never saw the man out of his depth, and has developed a kind of grudging respect for the man. They have exchanged words on occasions, but there has never been any held over resentment or bad feeling.
Dhormium is the dark horse. A quiet one generally except in the face of battle, when he seems to draw great strength from his god. He shares that strength generously with those he fights alongside. The dwarf is, in Marcus' eyes, a bit naive. And prone to bad jokes. But Marcus has no doubts about the generosity, or the strength, of his spirit.
