The eye is closed and these creatures didn't invade our world, so those soldiers at minimum wounded the eye. Have some survivors returned to the surface? I hope yes, and I wish they managed to escape the traitorous blades of their fellow Romans, pushed on them by the Emperor. The Centurion not only fought with honor, but left a vivid testimony of his own and his men struggles, and a warning we should embrace. May their spirits enjoy their reward in the afterlife
