Oh, Elleise. I'm so sorry to hear of your loss. :*(

The black raven, metal lantern, emerald eyes. All death or transition symbols. The metal lantern symbolizes a spiritual light for a journey (being made of metal, in this case, represents a cold or unfeelingness about the light). In other words, death really cannot have compassion or it might not be able to complete its task.
