But this actually proves my point. You've come on three times tonight just to make random comments. What's stopping you from popping in for a few minutes on any other night if for no other reason then to see if the topic has been updated or not? Yeah, you got nothing.
Because, like the Lore Carbon, he has been forced to abandon the cause.
Forced into hiding by the menacing RL, he now roams aimlessly the few times he can reach the Forums. His comrades out of reach, his life's work no longer accessible to him, Carbon is a ghost of his former self, a spectre forced to watch from afar as the Forums become something... different, unrecognisable. They are no longer his work. RL has seen to that, but he will one day return, and return the Forums to the path of Carbon!
Now substitute RL for Iron, and Forums for -UE_, and you've got an instant explanation for both Carbons with very little effort to go between the two.
Quite poetic for me, I think.
