Inquisitor Amaros is an Inquisitor of the Ordo Xenos and a member of the radical Isstvanian faction, currently missing from the Calixian Conclave. She is believed to have orchestrated the Mara landing massacre in order to cultivate useful servants from the survivors, though her and her faction's involvement in the massacre is without proof. Despite this, a number of the survivors who were not executed for potential taint found their way into the service of several Inquisitors with suspected links to Amaros; but this alone may have sparked the theory in the first place.
She is, however, known to have engineered the Trygor Xeno Plague by manipulating a cabal of smugglers and bio-pirates into modifying and distributing gene-engineered aliens as pets and guard-forms. This was meant to combat what she saw as the spread of potentially dangerous xeno-forms, and resulted in the deaths of countless citizens and the Euthanous Edict which in turn led to the purging on a dozen worlds of all non-human life. Amaros’s whereabouts are currently unknown.
