What are the Areloch

In a computer game called MedMyst, developed by Rice University, the Areloch are introduced in Mission 2 (of the 5) as a group of activists who blame the cities, like Neuropolis, for the cause and spreading of the pathogens. In Mission 3, they riot in the city square when the Neuropolis City Hospital is put under quarantine because of a boy with monkeypox, which you later find out about through the game.
