Rayya's story is one of loss, betrayal, and redemption. She hails from the Alik'r Desert, where her life was shattered by the Thalmor's invasion, which led to the death of her father and the destruction of her village. Consumed by grief and anger, she joined an army, seeking revenge against the Thalmor. However, after her comrades were betrayed by the Crowns, she became part of the Alik'r Warriors, fighting in the shadows and committing acts of violence against perceived traitors - including civilians.

Haunted by her past actions, Rayya struggles with guilt over the blood on her hands. Despite her warrior's exterior, she grapples with feelings of cowardice and shame, reflecting on her transformation from a hopeful soldier to a reluctant killer. 

Ultimately, she seeks to serve and protect her Thane, recognizing her allegiance while coming to terms with her past and the possibility of redemption.

Her voice should be mature, but not old. She is a seasoned and strong character with a troubled past. You may refer to vanilla Aela's tone and voice, but you do not need to resemble her.

Her emotions are expressed in subtle, intricate ways, never dramatic or flamboyant.
