Ariel symbolizes light and the direction South. She is amiable and thoughtful, and defined as the most beautiful and lushful Daeva in Elysea. Although it is assumed she has special abilities like the other lords, these abilities have never been revealed to outsiders.
Her appearance is revealed in a series of comics officially commissioned by NCsoft. In these comics she appears as a young woman wearing a hooded robe. She has long brown hair and yellow eyes.
When Israphel called for peace with the Balaur toward the end of the Millennium War, Ariel was his main supporter. She harbors deep disappointment and regret that Azphel's ignorance and recklessness led to the failure of the peace accord.
After the Cataclysm, she went to the lower hemisphere along with her followers, to defend the southern base of the Tower of Eternity. She became the leader of the Seraphim Lords and ruler of all Elyos.
She is aware of Lephar' presence, and even seems to know his true identity. Just before the events of Aion 2.0 her silhouette is seen in a cutscene in which she orders her deputy to prepare reinforcements for Kaisinel. In the official comic she is also seen entrusting Agent Viola with a special mission at this point (which is likely to dispatch to Iluma to investigate the weakening aetheric field). It is hinted that Ariel may be aware of the player's true identity at this point, and is thus sending Viola ahead to wait for him/her there.
- Ariel's original design was that of a woman with curly blonde hair, but later on this was changed. Her finalized appearance bears a heavy resemblance to the original design of Empyrean Lord Lumiel.
- In the comic her full face is only shown on panels that are set before the Cataclysm; in panels that are set after the Cataclysm her face is obscured by shadows. This is possibly meant to denote a change in her attitude.
