The original project that these characters are from had 7 characters...8 if you count 'invisible' friends...all of them are returning along with 2 more that got cut from the original project's script due to the page limit (16 pages). Adam, seen in the second strip, is one of those characters.
Slow Dawn can be thought of as an episode in the overall story, and sorry but there are no plans for a spacefever in this episode at least (although the mutiny may very well have occurred as a result of something similar...).
If you would like to read...and read...and read all about the original project's setting and script evolution you can check out the old writer's forum thread here
. Just don't bump it, it's almost a year old.
Anyway, there will be more to come, and it should come rather soon so be sure to check back!
