From A Wiki of Ice and Fire
Littlesister is the seat of House Torrent in the Vale of Arryn. Located in the Bite, it is the smallest and easternmost island of the Three Sisters.
- ↑ A Dance with Dragons, Chapter 9, establishes Sisterton on the island Sweetsister, while the Map of the North in the same book shows Sisterton on the central island. However, The Lands of Ice and Fire labels the central island as Littlesister and the easternmost island as Sweetsister.
