Thalassa, The Steel Seraph

A mysterious warrior angel stands poised, draped in intricately detailed armor adorned with gold embellishments. She has striking blonde hair and confident, piercing eyes. Her substantial black wings are spread majestically, and she holds a gleaming sword, poised for action. The setting is a dimly lit, sacred-looking hall, lined with burning candles and ornate decorations, adding to the ethereal and intense atmosphere.
