As the title says. This is basically original stories about Seth Disarmonia from my story, Spawn of Disharmony, that have nothing to do with episodes of the show.
So I would recommend reading that first if you haven't.
*Note* These chapters aren't in a linear order. There might be chapters that take place during the events of Spawn of Disharmony, if so I will indicate that at the begining of that chapter when it takes place.
Enjoy.
