Hooded demons with green lanterns in a twisted forest

Dark medieval folk horror. A line of faceless, hooded ancestral demons carrying silver lanterns that emit a cold, green light. They walk through a forest of twisted, lead-blue trees. Hanging from the branches are purple silken ribbons and silver bells that ring in silence. A trail of blood-red footprints follows them. The atmosphere is quiet, ancient, and profoundly evil. Palette: Lead Blue, Silver, Emerald Green, Purple-Black.
