Three Sisters

The Three Sisters are a group of three islands—Sweetsister, Longsister, and Littlesister—found in the Bite, located south of White Harbor and north of the Mountains of the Moon. The islands are controled by House Sunderland, who holds fealty to House Arryn of the Vale.
== History ==
The islands are called Sweetsister, Longsister, and Littlesister. The islands are ruled by the houses Borrell, Longthorpe, and Torrent respectively, although the archipelago as a whole is ruled by House Sunderland (though the exact location of House Sunderland's castle-seat is not clear). People from the Sisters are known as "Sistermen". Some of the lords of the Sisters are rumored to have webbing between their hands and feet, which is true at least in respect of the Borrels. "Sister's Stew" is a noted dish popular on the islands.
During the War of Conquest three hundred years ago, the Sistermen seized on the opportunity of the invasion to rebel against their overlords from House Arryn to side with the Targaryens. The rebellion came to an end when a Braavosi fleet hired by House Stark forced the Sistermen to surrender, and the islands briefly came under Northern control. Afterwards they were still administratively considered part of the Vale, now a subdivision of the unified Targaryen realm, but their support of the Targaryens was apparently rewarded with various local privileges, etc.
During Robert's Rebellion, Eddard Stark was on his way to the White Harbor, but was caught in a storm and ended at Three Sisters. Lord Borrel considered delivering him to Aerys, in order to prove his loyalty and to obtain a reward, but his son Godric (the current Lord Borrel) heard impressing news about the victories of Jon Arryn and Robert, and persuaded his father to spare Eddard and send him away.
