Ellid Abareim was an Accepted in the White Tower when Moiraine and Siuan were Accepted (NS, Ch. 8). Ellid took her test to become Aes Sedai one week after Moiraine and Siuan were raised, but she died during the test. Ellid wanted to choose the Green Ajah (NS, Ch. 12).
Ellid was extremely beautiful; she had wavy golden hair and brilliant blue eyes. Her skin was flawless and she was tall; she had an impressive bosom. However, she was very vain and liked to look at herself in the mirror (NS, Ch. 8).
Ellid always told people what she intended to do, and she invariably did it (NS, Ch. 8).
Moiraine did not like Ellid very much, mainly because she had very few faults (NS, Ch. 14).
Ellid was friends with Myrelle and Sheriam (NS, Ch. 8).
Vanity was a powerful fault, but that was her only real fault. Her only one. It was very hard to like Ellid. (Moiraine; New Spring, Chapter 8)
The beautiful Accepted who wanted to become a Green failed to come out of the ter'angreal... Ellid simply disappeared, and her belongings were taken away. (Moiraine thinking about Ellid; (New Spring, Chapter 14)
