That was fun. Of course, any Star Trek by DRG3 always is.
The inclusion of the two spoiler species gives me renewed hope of finally seeing certain story-lines in other parts of the lit-line resolved.
As far as their importance to the story goes, the species in question are minor players in the grand scheme. In the end, it really could've been any generic "Species A" chasing "Species B" and the story wouldn't have been that different (Heh. "Species A" and "Species B" actually work in this case).
