A range of Charms for the discerning Alchemical city-being, some collected from around the internet and some created by myself.
Avatar-Launching Silo
Contained within great steel and brass tubes, the Avatar-Launching Silos prepare and spin out facsimiles of the metropolis' ancient human-scale body. The avatars hold much of the power of the metropolis, but they are not drone-like creations nor mere limbs of the great metropolis. Each avatar has its own personality, its own identity, forged from a shard of the metropolis' expansive consciousness.
Champion Heart Efficiency Matrix: These submodules refine and expand the starmetal essence reservoirs within each avatar.
Titan Shard Reservoir: This submodule adds an enormous jade sarcophagus, stored in the depths of the Avatar-Launching Silo. Within this immense submodule rests a colossus-sized avatar of the metropolis.
Rapid Drone Operations System: Each avatar's sacrophagi is retrofitted with a jade-alloy casing, filled with safety webbing and Essence-injecting conduits. The silo itself is retrofitted with steam catapults and moonsilver rails that allow the launching of sarcophagi at distant locales at short notice. On impact, the sarcophagi shatters open to reveal the avatar within, showering all those surrounding with jade shrapnel.
Apogee-Shattering Hammer Deployment: This submodule replicates the effect of Rapid Drone Operations System for the Titan Shard Reservoir, allowing the immense colossi to be launched through the air and impact onto hostile positions.
Integrated Observation Network
With this charm, the patropolis is outfitted with sensor-posts linked by a network of glistening silver cables, extending throughout the city. At a moment's notice, any sensor-post can be reflexively activated by the patropolis' governing Alchemical, extending their awareness and allowing them to perceive all that transpires in the area. The system does not grant the patropolis omniscience, as the number of sensor-posts that can be activated is strictly limited by the Alchemical's ability to focus, and individual nodes are still vulnerable to attack and destruction.
Motile Surveillance Platforms: With this submodule installed, the individual sensor-posts become flittering mobile platforms the size of a small bird. They still cannot move beyond the city limits.
Visual Remembrance Matrix: Crystalline memory devices are installed into each sensor-post, allowing the visual memory of any post in the city to be downloaded into the Alchemical's memory. Auditory records cannot be stored within the crystals, and thus sound is absent from these recordings.
Discreet Vigilance Design: The sensor-posts are integrated into the patropolis' architecture in a way that makes them invisible to the casual observer, even while in use.
Sapient Scrutiny Spirit: A simple artificial spirit is downloaded into the observation network. It can be pre-programmed to alert the Alchemical guiding mind of any particular suspicious activity, bringing their awareness to that particular node.
Oneirological Monitoring System
Prerequisites: Integrated Observation Network
Unique moonsilver pentagrams are installed in the sleeping quarters of the city. Shadowy shards of the patropolis' consciousness are dispatched into the dreamscapes of the populat allowing them to monitor for dissent and other unhealthy impulses.
Cloud-of-Dreams Cortex
On installing this Charm, the metropolis extends sensitive starmetal antennae throughout her body. When activated, it draws on the unused processing power of the unconscious citizenry, improving the Alchemical's ability to conduct calculations and projections.
Catatonic Calculus Cognitor: When this submodule is installed, themettropolis gains the ability to directly seize control of the conscious minds of the city, temporarily turning them into catatonic outgrowths of her cognition systems. This act vastly increases the computational power of the patropolis, but at a terrible cost.
Shadow Government Dream
Prerequisites: Oneirological Monitoring System, Cloud-of-Dreams Cortex
Using complex metaphysical symbology and oneirological protocols, the central core and governing body of the patropolis are removed bodily from the realm of existence. Instead, it lives in a dream world held within the minds of populace, issuing orders and planning operations from a position of unparalleled security. This charm does not guarantee the compliance of the Populat, but it provides immunity for the government and the patropolis' core from most forms of physical and societal attack.
Subconscious Punishment Methodology: This submodule allows for punishments to be directed at members of the populat during their sleep, inflicting terrible tortures and nightmares on the maladjusted and the criminal.
Nocturnal Propaganda Inception: This submodule allows the patropolis to adjust the dreams of the populat, showing visions of industrial heroism and tales of nationalistic pride. It subtly adjusts mindsets, creating a populat more devoted to the patropolis and more vigorous in their labours.
Dreams-Within-Dreams Architecture: For the truly paranoid patropolis, this submodule constructs a secondary dreamscape within the first to house the Shadow Government Dream, placing it at even further remove from the physical world. This prevents foes with oneirological manipulation powers from easily penetrating the apparatus of the patropolis.
