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 comic version she also entrusts Viola with a special mission (which is probably to dispatch to Iluma to investigate the 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.
