House Castor

House Castor of Casterly Rock is the youngest of the Great Houses in Westeros. The head is the Lord Paramount of The Westerlands, the Lord of Casterly Rock and Protector of the West. The current Head of House Castor is King Jasen I Castor. Although not often considered so, House Castor is a cadet branch of House Rushing, having been founded by a legitimised bastard of King Petyr III Rushing.

During the reign of King Ryse IV Castor, the cadet branch, House Castor of King's Landing was founded.

Background
House Castor was founded by Ryse I Castor, the bastard son of King Petyr the Proud. He was raised amongst the king's trueborn children and was eventually allowed to ride in tourneys. After winning thousands of gold coins, his father put him to the task of slaying the evil Lord Haedon in the Westerlands. He succeeded and was rewarded with his own hold and lordship. He built Casterly Rock in the western mountains of the Westerlands.
