Trying to think outside of the box on this one so hear me out. The MoM gave his apprentices their new names. What if he gave a 7th person the name "Super" or "Superbia"? If the wording on the box is indeed "X Super" then i have a theory in mind. What if the person thats supposed to open the box is "Super" or " Superbia"? Using his knowledge of the future, the MoM could've prepared the box for someone in the future. We assumed the box was the MoM, but what if it were a "gift" designated for someone he refers to "Super"? The Sigil marks the traitor...so perhaps the MoM flat out tells us that the traitor is the owner of the box? Someone is looking for the box in KH3...so who knows. Does this spark any thoughts?
