House Baratheon of Dragonstone is led by Stannis Baratheon, the older of King Robert's two younger brothers. Lord Stannis has falsely accused King Joffery of impure heritage in order to claim his brother's crown for himself. Although he demanded fealty of all of Westeros, he commands a small host as his brother has also claimed the throne and received the allegiance of all of House Baratheon's traditional bannermen. However, Lord Stannis should not be underestimated, he is a fierce commander. He held Storm's End against a siege for the entirety of his brother's rebellion.
