Create a Halloween-themed image of a Roman legionary standing in an ancient military camp. The scene is spooky, with dark skies, a full moon, and mist creeping across the ground. The tents and fortifications are decorated with eerie jack-o'-lanterns, ghostly banners, and flickering torches casting long, eerie shadows. The legionary, dressed in traditional armor, holds a shield that has been painted with a skull, and his red cape flutters in the wind. The Roma legionary is fighting against a some ghost-like figure. Ghostly figures and creepy silhouettes lurk in the background, creating a haunted, yet powerful, atmosphere.
