I've never been big on the Glatorian era but the stories of the iron tribe once existing caught my interest. I know that the Great Beings modeled the Matoran universe after the world that once existed, so I was wondering about whether or not there could be Psionics, Gravity, Magnetism, Plasma, Lightning, Sonics, (Possibly Earth and Air?) and maybe even light? Or did the Great Beings simply get bored and feel like throwing in a few extra elements for the heck of it? (Or they could have done this because they simply needed them in the robot to do certain jobs to keep it functioning?) I don't know if there has ever been a mention of these ever existing or a comment made by Greg, so do any of you think they could've existed at some point? Do you think they could've been wiped out the same way as the Iron agori were? We don't have a large knowledge of the history of Spherus Magna before the shattering anyway. And if these tribes still existed (if they existed at all), then they would've gotten Element Lords right? What do you guys think each one would've looked like?
