Another Glorious Gone

Clandestine doesn't know who he is and never will. He's a lab rat trapped in the claws of the oppressive dictatorship of a city he lives. The only things that make him different are the scars on his face and the soft flickering flame in his heart; a flame buried under mountains of suppression, a flame that only starts to burn when a boy outside the walls finds him.
Who is this boy, why does he look so different and why,
why does he keep calling the lab rat Clancy?
