I wonder how much of a role this Lord and House will play in the series. I like his character.
And the Sigil -
House Bolton of the Dreadfort is an old line descended from the First Men and dating back to the Age of Heroes. Their sigil is a flayed man, red on pink.[1][2] Their seat is the Dreadfort and they are one of the most powerful lords of the North. The Boltons are best known for their practice of
flaying their enemies. According to GRRM, their words are "Our blades are sharp," while a common saying among the Boltons is "A flayed man holds no secrets."
The Boltons are an ancient and powerful house of the North who for many centuries were bitter rivals of the Kings in the North, the Starks of Winterfell. The Boltons achieved some successes against the Starks, flaying the skins of several Stark lords and hanging them in their stronghold, the Dreadfort. According to rumour, some Bolton lords even wore the flayed skins of their enemies - including the Starks - as cloaks. This practice has given the Boltons a sinister reputation, and it has been suggested that the legendary Night's King was a Bolton.
Approximately a thousand years ago, the Boltons finally swore fealty to the Kings in the North and agreed to abandon their tactic of flaying their enemies. However, three hundred years later the Boltons rose in rebellion against the Starks of Winterfell. The Stark armies besieged the Dreadfort for four years before the Boltons finally capitulated and dipped their banners once more. For many centuries the Boltons remained loyal to the Starks, although rumours persised that they continued to flay their prisoners in secret, and maintain a hidden chamber in the Dreadfort to display the skins of their enemies.
