The Honeywine is the second largest river in The Reach, behind the Mander. Its source is somewhere near Brightwater Keep, and it flows into the Whispering Sound in Oldtown. The lands around the Honeywine form the agricultural capital of the Reach.
Most Maesters believe that the mouth of the Honeywin has been a home to men since the Dawn Age. It has also been a notorious target for pirates, who would use it to raid the city of Oldtown, as well as the Citadel.
The Quill and Tankard is located on an island in the middle of the Honeywine river, as is the Ravenry of the Citadel. Guildhalls line the western banks, and the Starry Sept can also be found near the banks of the southern part of the river. A river road runs along the banks of the Honeywine.
