The term pillow-friends refers to a homosexual relationship between two individuals (usually female ones, making it a lesbian relationship). It is particular to the White Tower. Novices and Accepted commonly enjoy these relationships as comfort during the hardships of White Tower training, but are viewed as a thing of girlhood and are almost universally abandoned upon gaining the shawl. Some attempt to continue the relationships even as Aes Sedai though. This has the equivalent term of heart-friends in Seanchan slang.
