Foundation Security Force HierarchiesSite Security Officers: Standard guards armed with non-lethal and conventional weapons. They enforce daily lockdowns, patrol containment sectors, and act as primary line-of-defense fodder during routine entity breaches.Internal Security Department (ISD): The Foundation's secret police. They spy on staff, root out undercover spies from rival groups, and execute employees who leak classified database entries.MTF Epsilon-11 ("Nine-Tailed Fox"): The most famous heavily armed tactical unit. They deploy directly into ruined underground sites to re-contain escaped monsters and terminate rogue civilian survivors.MTF Sigma-3 ("Bibliographers"): Strikingly distinct from combat guards, this specialized occult unit infiltrates magic locations like the Wanderer's Library to track down reality-bending anomalies.Sentient Humanoids & KillersSCP-076 ("Able"): A resurrected immortal warrior inside a stone coffin. He possesses superhuman speed, summons blades from thin air, and lives purely to slaughter anything in his path.SCP-073 ("Cain"): Able’s polite, cybernetic brother. Any damage inflicted upon him is immediately reflected 100% back onto the attacker, and his presence instantly rots plant life.SCP-1440 ("The Old Man from Nowhere"): An immortal wanderer cursed by Death. Wherever he walks, human structures collapse and nearby people die, forcing him into eternal isolation.SCP-2006 ("Too Spooky"): A shapeshifter that loves terrifying humans. It only mimics cheesy B-movie rubber monsters, but it possesses the reality-destroying power to exploit mankind's true deep fears if it ever learns them.Reality, Concept & Mind HazardsSCP-055 ("[Unknown]"): A self-keeping secret. It is an "anti-meme," meaning anyone who looks at it immediately forgets what it is. Staff can only successfully remember what it isn't. Jessica: the new recruit that is what you guessed, the pick me.
