Unmasked
This creature is an amalgam of human and humanlike entities from a million conterminous worlds—sa chain across the multiverses that exists in and can perceive all of them at once.
Its features and limbs blend and fade into odd, fractal-like averages of positions, meaning its arms "unless completely still" are blurred motion trails, and its face is averaged into a pink, seamless mass. Still, despite its hideous nature, it moves with intelligence and purpose.
It manifests in this space-time only at night, for reasons not fully understood. It seems drawn to prodigies, cyphers, and mask-forms, and though its ultimate goals are unknown, it seems eager to locate and destroy the prodigies. It is attended, usually, by the Faceless—humans who were affected by the August 22 incident and who can now be "hijacked" by some sort of non-human intelligence. If this thought experiment is taken to its conclusion, it is logical to assume that, like the Faceless, Prester John is connected to one, fixed human form in town who has no knowledge of this non-human intelligence occupying their body. If that human vessel is destroyed, will Prester John perhaps cease manifesting? It is also seemingly connected to the prodigies, as they often catch glimpses of what it is doing when they dream. The name (either given to it by itself, or through some sort of strange psychic bond with its victim) is the name of the legendary Christian king of the East—a historical being who never actually existed. Whether or not this name has a deeper meaning is unknown.
Motive: Destroy the teens occupied by mask-forms
Environment: Anywhere in Boundary Bay
Health: 99
Damage Inflicted: Major wound (12 points)
Armor: 5
Movement: Short; long when flying
Combat: Prester John can cause rifts in space-time anywhere within a half mile (1 km). These fractures in causality make creatures and objects in them crack, twist, and distort in an otherworldly manner. Prester John can cause these "bubbles" of unreality to expand and engulf multiple targets, inflicting 8 points of damage to everyone within the radius.
In hand-to-hand combat, Prester John can attack all targets in melee range at once, as its limbs contort, blur, and swirl in waves of probability. This attack inflicts a moderate wound (6 points).
It can consume a cypher by touching it, instantly regaining the cypher's level in health points up to its maximum health of 99.
Such cyphers are destroyed in the process.
Interaction: Attended by the Faceless, which defer to it, Prester John appears and strikes when a prodigy teen is most vulnerable at night, usually when they are alone. Its goal is nothing less than the absolute destruction of the teen "containing" the mask-form.
It moves with a staggering gait, but sometimes it will lift and float into the air, as if carried by some invisible force.
It will attack relentlessly, and it is clearly intelligent, utilizing tricks and feints to get the prodigy or the mask-form to step into preset ambushes. When it kills a prodigy teen, it consumes their mask (in the same manner it can consume cyphers), as if it were "feeding."
Use: A teen the PC knew to be a prodigy is found, smashed up and murdered. The following night, the PC sees a strange, shaking figure in the dark outside their home. Prester John has come for them.
