C5 Alpha Alpha One

From Tardis Wiki, the free Doctor Who reference

C5 Alpha Alpha One was a minor domestic cleaner in Paradise Towers. After being damaged by Blue Kangs, it retreated to Level 27 to make repairs. Finding it couldn't leave the floor, it reverted to its prime command and cleaned the entire floor. Apartment 17 was filled with books, and C5 read them so that it could learn how best to tidy them. Reading the books made C5 begin to question the world, and, if it could not receive commands from Kroagnon, then it wasn't an infallable god.

C5 then turned Level 27 into an infirmary, and made sure no one could access the floor by changing Paradise Towers records and making sure only elevator 12 could access the floor. It then saved, kangs Staff Alleviator, Emergency Exit and Bin Recess, as well as caretaker Fleming, and treated their wounds and gave them a home on Level 27.

After Kroagnon was defeated, they left Level 27 to help build a better Paradise Towers. (PROSE: C5)
