The Sunset Sea is roamed by swordfish, seals, and whales, and Ironman's Bay and coastal regions are populated by various fish and shellfish. It is unknown if legendary sea dragons exist in the sea.
In the south, the Redwyne Straits and the Arbor divide the Sunset Sea from the Summer Sea to the southeast. North of the Arbor is Whispering Sound with Oldtown, Blackcrown, and Three Towers. Farther north in the Reach along the Sunset Sea are Bandallon, the Shield Islands, and the mouth of the Mander.
Beyond the Iron Islands is a peninsula of the north which includes the Flint Cliffs, Cape Kraken, and Flint's Finger. The Fever River and the Saltspear flow into Blazewater Bay. North of the peninsula are the coastlines of the Rills and the Stony Shore. Even further to the north are the Bay of Ice and the forests of Bear Island, Sea Dragon Point, and the wolfswood. The Sunset Sea continues north beyond the Wall along the Frozen Shore.
In Songs the Drowned Men Sing, Maester Kirth suggested that the Seastone Chair was created by a people from west of the Sunset Sea, and Archmaester Haereg proposed that the ironborn of the Iron Islands descend from these visitors.
The ironborn of antiquity used their longships to dominate the western coast of Westeros, initially raiding the First Men of the green lands but eventually turning to conquest in the era of driftwood kings. During the reign of Qhored Hoare the ironborn controlled the western shore of Westeros from the Arbor to Bear Island, but his gains were gradually lost by his descendants. The First Men of the continent eventually fought back with longships of their own and used stone fortifications to defend against the raiders, and skilled Andal sailors accelerated the ironborn's fall.
Claiming the riverlands, King Arlan III Durrandon extended the borders of the Kingdom of the Storm from the narrow sea in the east to the Sunset Sea in the west. However, his descendant, Arrec, lost the riverlands to Harwyn Hoare, King of the Isles and the Rivers.
Lord Alton Greyjoy, known as the Holy Fool, attempted to conquer lands beyond the Lonely Light. Lord Dalton Greyjoy, the Red Kraken, ruled much of the Sunset Sea during the Dance of the Dragons until his murder at Fair Isle. Lord Dagon Greyjoy also attempted to make the lands along the sea subject to the ironborn again, but was eventually defeated by House Targaryen.
A Clash of Kings
A Feast for Crows
During the kingsmoot, Gylbert Farwynd, Lord of the Lonely Light, puts his name forth for King of the Iron Islands, supported by three champions who are his sons. He promises to lead the ironborn to lands beyond the Sunset Sea where every man would be a king, but his claims are quickly dismissed.

No one has ever crossed the Sunset Sea to learn what lies on the other side.
