The First Mark:
Unlike the second mark, this one is not as easily explained, While it is a physical object, it is one not often used as a weapon, but think of it as a household appliance. A latern. This isn’t really a weapon that can be used in effect, but there is one important thing about this Latern that makes it co-existence to Morte’s ability. It has a demonic spirit that lives deep within the core, and with that is how it can correspond with Morte’s power.
But more about this demon spirit, like where did it come from? How did it get trapped in this Latern? How did Morte come in possession with it?
All questions that can be answered easily, but not so easily. While these figurative questions are based off of assumptions, they can be related to the history of both Morte’s Marks and his own personal bio.
