From the "Game Of Thrones Wiki":
Stannis Baratheon is a major character in Game of Thrones. He is played by starring cast member Stephen Dillane and débuts in the second season. He is mentioned in the first season but did not appear. Stannis Baratheon is the Lord of Dragonstone and the oldest brother of the late King Robert Baratheon. Because of rumors that Robert's heir Joffrey is a bastard born out of an incestuous affair, he has claimed the Iron Throne and proclaimed himself the rightful King.
Stannis is the secondborn son of House Baratheon, the younger brother of the late King Robert Baratheon and older brother of Renly Baratheon. He served on his brother's small council as Master of Ships, and holds the title of Lord of Dragonstone. During the first season, he is at home for an extended stay.
The sigil of his household is the flaming red heart of the Lord of Light with the stag of Baratheon in the middle.
Although mentioned during the first season, he didn't show up in the series until the second season premiere.
