Two (The Taking of Planet 5)

Investigator Two (originally Eighteen, later Spicy Archon Stories) was an agent of the Celestis.

The Celestis elevated Investigator Eighteen to single digit status when they sent it on a mission with Investigator One. On the surface, One and Two were sent to the wider universe to find out what had caused a Celesti to not only cease to exist, but to have never existed. During that investigation, Two was to watch One, whom the Celestis feared had gone rogue; if this was confirmed, Two was authorised to eliminate One. Upon discovering Two's true purpose, One attacked her and bashed her skull into a pulp; however, the nanites in Two repaired the damage, reconstructing its memories so it believed its mission was to kill all humanoids.

Two eventually regained enough memory to remember Mictlan and TARDISes, and it developed a urge to return home. Upon finding Hume, it decided to eat his brain and absorb his knowledge so it could build at least a rudimentary TARDIS and return to Mictlan. While Hume and Two fought, Fitz Kreiner was able to finish repairing the Celesti fictional generator and he used it to turn Two into a work of fiction: a 1930s-looking magazine called Spicy Archon Stories.

The Book of the War described one Investigator Eighteen who was known as one of the most eccentric Investigators. He often staged elaborate fictional trials while escorting new servants from the outside universe to Mictlan. (PROSE: The Book of the War) Whether this was the same Investigator Eighteen who was later elevated to Two is unclear. (PROSE: The Taking of Planet 5)
