A female Dungeons & Dragons 5.5 Vengeance paladin standing ready for battle inside a dark cultist lair. She is a striking Irish warrior woman with pale freckled skin, fiery ginger hair, intense green eyes, and a grim determined expression. She wears worn battle-scarred plate armor, scratched steel, dented edges, leather straps, dark cloth underlayers, and a rugged spangenhelm inspired by early medieval warrior helmets. She grips a massive warhammer, heavy and brutal, ready to strike. Around her are black candles, occult symbols, blood-red banners, broken ritual circles, skulls, chains, sacrificial stone altars, hooded cultist silhouettes, and flickering torchlight.
