Avant-poste de falaise de dark fantasy

A dark fantasy matte painting of a bleak hilltop encampment overlooking a vast cursed wasteland at dusk. In the left foreground, a ragged hanging banner reads "The Pale Lodge Outpost" in large black hand-painted letters, attached to wooden poles and weathered by wind. Beside it stands a tall carved totem post topped with a black raven and draped with bones, skulls, and tattered ornaments. The camp itself contains 4 visible canvas tents: 2 large central tents, 1 medium tent on the left, and 1 smaller tent on the right, all in dirty beige fabric with black occult sigils painted on them, held by ropes, spikes, and crooked poles. Around the tents are 5 hooded human figures in dark robes, standing still like sentries or cultists. Near the center-left is a small campfire casting a faint orange glow. In the right foreground sit 2 brass-and-iron astronomical or ritual instruments on stone pedestals, resembling armillary spheres or astrolabes. The ground is uneven black rock at the edge of a cliff, with scattered stakes, lanterns, banners, and ritual posts. Beyond the outpost stretches a desolate valley of ash-colored plains, winding pale waterways, jagged rock spires, and distant mountain silhouettes. On the horizon, slightly right of center, a sinister dark castle rises from a lone hill. The sky is filled with enormous turbulent storm clouds, with 3 flying creatures or birds silhouetted in the distance and a break in the clouds casting cold, sickly light across the landscape. Use a grim, painterly, highly detailed style with muted sepia, charcoal, umber, and gray tones, dramatic atmospheric perspective, cinematic composition, and the mood of a foreboding fantasy frontier outpost at the edge of a dead world.
