- History of the Tumori Tribes - 22 October 2025
Of alien parasites and the history of fear. "Siren System natives. Hostile, creepy, sort of parasitical body snatchers. But as far as I know, they avoid human hosts." (Sovereign Fleet Captain Annika Finch) "Autopsy of sentient alien lifeforms is strictly forbidden by the UNSS law. But 'nullo actore, nullus iudex' or 'Where there is no plaintiff, there is no judge'... And the Siren System is truly a land of no judges. So when the Research Division finished the first batch of autopsies, two things became clear: the Tumori are parasites that can possess hosts from the regnum Plantae et Animalia without difficulties. And athough they are undoubtedly able to enter, live in, and control even Hesperidian, human, or Fossorian hosts, they have done so only in a few documented cases, which makes these 'aliens' quite special. Gergielarh, lower your hands. I already know what you want to ask. 'Prof…
