Thalios scratched his chin in contemplation as both he and the Shambler viewed the initial destruction and then the thwarting of the gigantic worm created by the Shambler via dimensional shifting of some sort. The concept itself eluded him as to how he could do something similar but instead caught his attention to a very different idea. If large scale would not work then small-scale would be better. "I have an idea, Aforgomon. If big is not better then perhaps we must think.. small." His mind was an open book the the strange being, Thalios allowing him in without any hesitation. A favor was a favor. The concept was quite simple really. A virus had nearly annihilated the alien species once and many still remembered. A miracle had cured the pestilence, not their medicine, which struck Thalios as obvious to the answer.

With their gods gone it would finish the job. Advanced medicines still took time, mortal time, to come up with an answer. Thalios' mind went through the plan to open small little rifts, thousands of them, throughout the ship to release a nightmare version of the deadly disease to every inch of the ship. This horror of a sickness spread fast and could kill faster as it made the brain swell to nearly three times its size, cutting off lungs from air as the throat constricted and oozing rashes spread across open skin. A single cough in a room could infect every last person who came in contact. The best part? The virus was particular to the alien anatomy in the same way a cat could not get a human disease, the humans would be unable to be effected by the alien disease. 
Swirling purple flowed from his body like smoke to waft into a small portal, his deathly toxin seeping through a portal to spread in a miasma of death. To Thalios' thinking, only the Aliens who were off-station on the human world would be spared the horrific end he would give these creatures.
