In Star Trek: Online I don't think they were part of the Species 8472 invasion but what would you all say to doing something with the Cardassian True Way group? The True Way could, in our game, be infiltrated by a member of Species 8472 instead and used as a cat's paw to sow strife and discord in the region. It would tie nicely into the unknown aliens and Mirror Universe encounters that Nathan Knight's had, and it's something that could easily be something that Thera knows about and is interested in dealing with in light of her relationship with Garak and her residence on Cardassia.<br/><br/>The disruptions with the Worm Hole that Thera's post brings up could be attributed to the True Way screwing around with the Mirror Orb they have as part of efforts to free the Dominion fleet that was trapped in the Worm Hole by the Prophets. The Species 8472  infiltrator could plan to simply unleash the Dominion fleet or perhaps, more cannily, plan to take control over the Dominion fleet by posing as a Changeling using its own shapeshifting abilities to fool the Vorta and Jem'Hadar.
