The Reach

The Reach is one of the constituent regions of the continent of Westeros, and was formerly a sovereign nation known as the Kingdom of the Reach before the Targaryen conquest.

The Reach is ruled from the castle of Highgarden by House Tyrell. It is one of the larger regions of the Seven Kingdoms. Bastards born in the Reach are given the surname Flowers.

In the books
In the Song of Ice and Fire novels the Reach is the most fertile part of Westeros, blessed with vast, blooming fields of crops and flowers, and numerous and well-populated villages and towns. The Reach is the most heavily-populated part of Westeros and is one of the richest, though not as rich as the Westerlands ruled by House Lannister. Due to this, the Tyrells can traditionally field the largest army in the Seven Kingdoms, almost as large as any of the other two combined.

The Reach is watered by the immense River Mander and its many tributaries. The borders of the Reach are held as the Sunset Sea to the west and south-west, the Red Mountains of Dorne to the south-east, the hills of the Westerlands to the north-west and the Blackwater Rush to the far north-east. The Reach is linked to the capital at King's Landing by the Roseroad.
