The entire crew got imprisoned in an evil artificial dimension created by terrorists. Things looked bleak until Viridian happened upon a weird shadow machine, which he used to clone himself. The copy of Viridian broke the crew out of the dimension, destroyed it using its creators' very own flawed prototype weapon, and used the shadow machine to escape.
Unfortunately, this has had some unintended consequences. All the original Viridian knows is that his crew have been locked up again, this time semi-legitimately for transdimensional vandalism. As yet another rescue mission unfolds, it becomes clear that he's made a terrible mistake. Can he put the cosmos to rights?
