Arc 1: Past – Episodic, focusing on the TCS (precursor to the Magometry Research Agency) and with a variety of antagonists, one of whom (Janelle Donovan) recurs.
Arc 2: Present – More unified, focusing on the MRA proper and with one consistent antagonist.
Past arc has about 9 chapters, present arc has about 14. 23 total, with a ‘series finale’ consisting of three parts, a prologue/epilogue not counted, a few intermission chapters – mostly backstory-oriented – also not counted, and possibly some Miscellaneous which don’t fit anywhere.
If I actually reach the big series finale it’ll probably be followed up by Prismatic, ‘episode 24′ and/or The Big Side-story Movie.
It has two sets of bookends, due to kinda Anachronic Order; chronologically it starts with Darian and ends with Julien, but in the actual story structure the prologue and epilogue consist of two conversations between Miles and Janelle / Tobias and Janelle.
Wow, this might actually exist at some point…
