The Arcane Sentinel in Shadows

a mystical, hooded character, dressed in ragged dark fabric, is positioned on a textured ground with a cityscape in the background. the character's body glows with vibrant blue lightning, particularly on the left side, and a blue glow is emitted from their open right palm. a sharp, luminous blue sword is laid out on the ground in front of the kneeling figure. the distant city lights twinkle against the dark night sky.
