Her breastplate features a large blue and gold cross, symbolizing her holy order. She wears a royal blue gown with puffed sleeves under her armor, with delicate gold accents and embroidery. Her weapon is a masterfully crafted longsword with a glowing blue blade, featuring a cross-shaped hilt in gold, radiating faint magical energy. She holds the sword aloft with authority, her icy blue eyes scanning the horizon. Her golden blonde hair is tied into a long braid, with a few strands framing her face. The sunlight casts a faint halo around her, creating a divine aura. The gothic cathedral in the background towers with sharp spires and intricate stonework, its stained glass windows casting faint hues across the stone. The atmosphere evokes a sense of duty, grandeur, and divine purpose.
