A river of words flowed between us.
Aech is a major character in Ernest Cline's Ready Player One.
Aech is Wade's best friend , alhough the two didn't meet in-person until much later, Wade claims that they've always shared a great connection. In the beginning, it is clear that Wade and Aech shared many interests — movies, musics, videos games, and the hunt for Halliday's egg.
Their shared quest for Halliday's egg brought about friendly competition. Aech and Wade would spend their time together discussing pop culture, Almanac findings, the hunt, and girls.
He also attended OASIS public school, at OPS #1172.
GIGANTIC SPOILER ALERT!
In the real world Aech is a heavy-set African-American girl named Helen Harris. Helen uses a Caucasian Male appearance and voice for her OASIS avatar in order to be more easily respected by her peers.
Within the OASIS, Aech is a PvP (player versus player) competitor. Wade notes that his friend is one of the highest ranked members in both the Deathmatch league and the Capture the Flag league, making a "quite a bit of dough" in the process. This partially explains how Aech is able to afford the large chatroom, the Basement.
It is also mentioned, in the beginning of the novel, that Aech is more famous than Art3mis.
Aech's avatar is a tall, broad-shouldered Caucasian male with dark hair and brown eyes. Wade once asked Aech if this avatar represented a real-life appearance; Aech responded by saying: "Yes. But in real life, I'm even more handsome."
Helen, or Aech, is intellectual, dedicated individual. This can be observed by her high competitive ranking within the OASIS, her "elite" knowledge of video games that rivals Wade's, and her long-term hunt for Halliday's egg. She also appears to be quick-witted and humorous. This is demonstrated by her exchanges with I-r0k and Wade in the Basement.
Real Life Edit
Outside of the OASIS, Aech is a "heavy-set, African-American girl." She has short, kinky hair and dark skin. When Aech and Wade meet in-person, Wade notices that the Cheshire grin on her avatar's face is identical to her grin in real life. Her real name is Helen Harris, and she is about 18-years-old.
