Dark Fantasy Isekai Novel Cover

A dark fantasy anime light-novel cover in a vertical composition, painted with detailed dramatic brushwork and moody cinematic lighting. Show three young women posed in a triangular arrangement against a ruined medieval city engulfed in flames at night, with smoke, embers, collapsed timber buildings, and a large stone castle on a rocky hill in the upper background. In the foreground center, place a beautiful young woman with long flowing {argument name="hair color" default="powder blue"} hair, wearing an off-shoulder blue corset dress with white frilled sleeves and lace-up bodice, one hand lightly gripping her chest, her expression serious and vulnerable. Behind her on the left, place a tall woman with silver-white hair tied in a high ponytail and a white headscarf, wearing a modest black dress with a high collar and front fastenings, standing in profile with a stern, unreadable presence. Behind her on the right, place a blonde girl with twin braids under a brown hooded cloak, pale blue-green eyes, holding a black book with a star-like emblem on the cover close to her chest, looking sideways with a guarded expression. Use layered character overlap, strong contrast, and slightly desaturated colors except for warm firelight and deep reds. Add large vertical Japanese title typography along the left side in distressed calligraphic style: 「異世界辺境伯領」 in black and dark red, plus two smaller vertical text blocks near the lower left reading 「現代の倫理観を捨て」 and 「権力と暴力で泥臭く生き延びます」. Add a decorative compass-like emblem near the lower left and a large bold vertical subtitle 「転生」 at the bottom left. Ornate corner filigree, gritty light-novel cover design, intense isekai war atmosphere, high detail, premium illustrated novel cover.
