Do you guys recall any weird or unexplained events in the history of the Matoran Universe? I don't refer to events that the Matoran didn't fully understand -- I refer to events that we, as an audience, didn't understand and still don't. Little unresolved mysteries and loose ends... aka plot holes. You see, I have an idea pending for an epic that includes characters subtly manipulating the MU since the Time Before Time, and I figured I'd use this opportunity to try and make sense of the plot holes and mysteries. Thus far, I've got "who hid the Great Disks?", and that's it.
