The Yellow in this spiritual portrait represents Stannis' dominant trait, his pragmatism. In Introverts, the dominant trait is directed inwardly, and spiritual portraits use a long horizontal line to represent this. He demonstrates this trait in the way he abandons faith in the Seven for a religion that promises him personal gain.
The Green in this spiritual portrait represents Stannis' auxiliary trait, his rationality. In Introverts, the auxiliary trait is directed outwardly, and spiritual portraits use a vertical line to represent this, because it is more evident than the dominant function. He demonstrates this trait in the way he is able to fearlessly lead his army on the field of battle, and most tragically, in the way he treats his daughter, the Princess Shireen, when she dies.
Lord of Dragonstone
Like his personality, Stannis Baratheon's spiritual portrait is extreme. It looks very ....
To say that Stannis is
cold is an understatement. In one scene he describes his relationship to his older brother Robert Baratheon thusly:
He wasn't mybelovedbrother. I didn't love him. He didn't love me.
Like Tywin, Stannis is an extremely unpleasant person. He is interested only in power. Honor is for dummies.
Jon Snow: I pledged my life to the Night's Watch.
Stannis Baratheon: You're as stubborn as your father, and as honorable.
Jon Snow: I can imagine no higher praise.
Stannis Baratheon: I did not mean it as praise. Honor got your father killed.
Like so many of the other characters on Game of Thrones, Stannis is a tragic figure. Unlike many of the others, it's difficult to feel any sympathy for him.
