The Sea of Lost Lights is a large sea on Roshar's subastral of the Cognitive Realm.[1] It is bordered by the Sea of Souls, the Expanse of the Broken Sky, and the Expanse of the Vapors. In the Physical Realm, this area would be the eastern part of the continent of Roshar, including Alethkar, the Frostlands, the Shattered Plains, and Thaylenah.[2]

It is not clear why this sea is called the Sea of Lost Lights.


The southern regions of the Sea of Lost Lights, and its adjacent landmasses in the Cognitive Realm, are well mapped.[3]

Bodies of water[edit]



Connecting the land makes up rivers in Shadesmar are various channels.


Shallan, Azure, Adolin, and Kaladin get trapped in the Sea of Lost Lights after they attempt to use the Oathgate in Kholinar.[citation needed] Azure seems very knowledgeable about the place and says the way to get back to the Physical Realm is through Cultivation's Perpendicularity at the Horneater Peaks.[citation needed] The rivers in the Physical Realm become peninsulas here made of an obsidian-like material. There are plants growing on this, and Syl says they grow just like normal plants. They travel along the peninsula to a lighthouse at its end. Inside this lighthouse is a man, Riino, who Kaladin thinks is Shin, but is likely from Sel as he references the Korathi god. He claims that his orb can see the future. Kaladin looks in this orb and feels strongly that he needs to go to Thaylen City and thinks that Dalinar is in grave danger.[citation needed]

They get a ride on a boat sailed by lightspren, or Reachers. The boats are pulled by Mandras, which have heads the look like Luckspren. The Reachers have fabrials that can create water. They are sailing to Celebrant, a city on an island that is the Sea of Spears in the Physical Realm. The captain says that they have perfect spheres there that never run out of Stormlight.[citation needed]
