I see this as a good first effort. It is solid material and I urge all fans of the OSM to obtain a copy, read it and present their opinions here.
I do not want to give away the plotline - other than what has already been discussed here, re: Mystron, etc.
I will say that the byplay at the end between Colossus Rex and Orbitron (about Orbitron's nudity) was quite amusing. As was the earlier bit about Rex's excuse for being late for the meeting.
But, let's not make C. Rex into a buffoon...
Further comments from my side may be coming; however, I do not want to prejudice readers with respect to their own comments. Rather, I'd prefer for now to facilitate discussion and enter the "fray" once it is started.
