Farangis serves as a priestess of Mithra dispatched by the temple to protect Prince Arslan. Chosen as his guardian at birth to fulfill a prophecy, she suspects her formal temple dismissal stemmed from jealousy over her beauty among fellow priestesses. Her loyalty to Arslan begins as an ordained duty but transforms into authentic devotion as she witnesses his character and judgment firsthand.

Her past holds a profound loss: the death of a man named Eagleelus years before the main events. This tragedy shaped her reserved nature; her affections remain bound to his memory, coloring her responses to others' romantic advances. She maintains a cool-headed, rational approach, prioritizing fairness and spiritual harmony while acting with perceptiveness and grace. Her commitment to ending conflict extends to pragmatic combat when essential, though she views battle strictly as a last resort to defend her values or allies.

In combat, she wields the Bow of Mithra and a sharp sword, employing precision strikes and strategic efficiency. A unique whistle worn around her neck enables communication with Djinn, allowing her to summon or command these spirits in critical moments. She occasionally performs rituals invoking divine power, using overt magic only in measured, situational ways. Acute perceptiveness enhances her physical capabilities, letting her detect threats or hidden truths others overlook.

Her interactions reveal further dimensions: she adopts a sisterly role toward Alfreed, offering guidance and support. Conversely, she consistently rebuffs romantic advances from Gieve and Kubard, responding with swift dismissal or irritation. Her dynamic with Arslan evolves from detached obligation to deep respect, particularly as she observes his empathy and developing leadership.

Visually, she possesses shimmering dark hair, piercing eyes, small red lips, and a curvy figure. Her attire includes a revealing white tunic with a draped hood, a white skirt, a white cape, and thigh-high brown boots. Constant accessories are red teardrop-shaped earrings and the Djinn-commanding whistle. This distinct appearance underscores her dual role as spiritual figure and warrior.

Her narrative development shows a transition from fulfilling a predetermined role to embracing active investment in Arslan's cause. Initially aloof, she becomes an integral part of his retinue, balancing spiritual duties with frontline combat. Her backstory involving Eagleelus and her temple experiences continues to inform her resilience and focused dedication, though she seldom discusses these personal elements.
