The Reach is one of the constituent regions of the Seven Kingdoms on the continent of Westeros. It is the second-largest of the kingdoms behind the north and is considered the most fertile and heavily-populated part of Westeros.
The Reach is considered the home of chivalry in Westeros. It is the place where knighthood is looked upon with the greatest reverence and esteemed the most. It is also the place where the rules for tourneys are the most stringent and managed.
The Reach is ruled from the castle of Highgarden by House Tyrell. Notable houses have included Ashford, Caswell, Crane, Florent, Fossoway, Gardener, Hightower, Merryweather, Mullendore, Oakheart, Redwyne, Rowan, Tarly, and Vyrwel. Noble bastards born in the Reach are given the surname Flowers.
