bas-relief carving on a textured, dark surface

bas-relief carving on a textured, dark surface. Three figures in classical attire are depicted in profile. The leftmost figure, facing right, holds a sword aloft in its right hand. The middle figure, also facing right, holds a staff in its right hand and gestures with its left. The rightmost figure, facing left, holds a staff with both hands, with its left arm extended upwards. The figures are rendered in an orange-pink hue with black outlines. The carving is set within a concrete structure, with rough, light-colored stone visible above and below the carved panel. The concrete is weathered and shows signs of age and repair. The overall impression is of an ancient or historical art piece integrated into a rustic architectural element, possibly located outdoors in a place like Sinemorets, Bulgaria, given the natural stone and weathered concrete.
