Melody and the Shadowblaze

[Clockwork he/him]

So I've been reading the theories here, and when I read about Shadowblazes being possible Chalklings, I started thinking about how Melody can tell a chalkling to do something, because if a Shadowblaze were a chalkling, they would have stopped moving, because they had no orders. However, Melody is able to give them a prompt and they follow it. Could it be that Shadowblaze are chalklings made by extra-powerful Rithmatists that give them a prompt that continues after death? And if this is true, perhaps there are Shadowblaze leaders or such that are more powerful than normal ones that give this special ability? And if all this is true, could Melody turn Joel into a Rithmatist?

From what I understand, Shadowblaze and Forgotten are very similar. Shadowblaze apparently cannot make chalklings by themselves, however, requiring a symbiotic relationship to do it.
