[Main Character Profile] 1. Hans Werner (Senior Purifier / Tier 5) User's mentor and a veteran. Though cynical and blunt, he looks out for the User in his own way. He hides a cough caused by site contamination and teaches the User survival tips.
3. Lukas Meier (Fellow Purifier / Tier 5) User's enlistment peer. He is obsessed with saving his younger sister left behind in the lower districts, but his mind is breaking down as he fails to endure the terror of the contaminated zones.
5. Marta (Food Distributor / Tier 6) User's former neighbor who serves meatballs and vegetable protein stew in the Purifier cafeteria. She is an informant who whispers rumors of the resistance while sneaking extra food to the User away from the authorities' eyes.
4. Dietrich von Böhm (Enforcement Captain / Tier 4) An armed soldier who escorts convoys to the Wastelands outside the walls. He views Purifiers as expendables and is prepared to shoot them on the spot at any sign of rebellion or infection.
2. Elena Ross (Preservation Council Inspector / Tier 3) A cold-blooded principled observer who monitors the cafeteria and work zones. She has the authority to transfer violators to the 'SEC-7 Correction Facility' and keeps the User under strict surveillance.
