oh dear, there's a piece of mysterious metal in my flywheel

So after a long hiatus in riding my 85 Spree (was getting poor vacuum on my carb which in turn killed most of my starter system), I give it a ride and it's feeling a little odd. It's not going very fast and the engine appears to be shaking. I pulled it over in a safe place to have a looksie as my first thought was that I'd just not tightened the shock bolt properly and it went careening off somewhere, but that was not the case.
I started it back up while gazing at the engine/innards to see if i could see/hear the problem from up close, but it only ran for about a second before the engine straight up seized. I heard a big ol' "CLUNK" sound from the rear end of the engine, so I popped off the cover to see what was up, and lo and behold the belt was stuck on something. I cleaned it out and found many little pieces of what looked like aluminum shavings, including one that was wedged between the belt and the rear end of the belt assembly. I rotated the belt a little bit to see/hear if all was well now and I heard something rattling inside the flywheel (that's what the rearmost wheel is in the belt compartment, right? feel free to correct me if it's not)
A closer visual inspection revealed that it looked like there was some kind of inner wheel that has disconnected and has all but melted/shaved off, I got a pic from the back

Any ideas? I tried to get the wheel off with my adjustable wrench, but nothing doing. Didn't have my universal holder with me.
