RP-M Annabelle: The Urban Tumult of Eolia
Eolia is a pastoral land of hilly grasslands and flat forests with a beautiful lagoon on its southeastern coast. It is a fairly baseline and mundane land rich in mineral resources with only three oddities to speak of. The first is that most of its natural rock demonstrates unusually vibrant coloration; quartz hues as red as fresh blood and blue as the noon sky, and everything in-between. The second flavor of local strangeness is its unusually weak realm borders; Eolia penetrates into and transitions seamlessly to match its Myriad neighbors. The third are the cassimis, a race of magical doll-like servitors that appear to be the realm's true natives.
The realm is in a state of early- to mid-Industrial Revolution; early trains, automobiles, and mechanized fighting vehicles are quickly replacing animals in virtually every area. Research and innovation is driven by the exchange of ideas between the many drifting species that have over time settled the land. Iron and coal are lifted from the earth to fuel the industry, the colorful fieldstone and mining rubble used to create beautiful and resilient stone buildings adorned with arches and flying buttresses that glitter dazzlingly in the sun. The year-round temperate climate, abundant resources, and tireless devotion of the native doll girls makes for quite an attractive place to live.
Of course, so many species and realm connections in close proximity are not without their downsides. Eolia is subject to frequent intrusion, either in the same of capturing its resources or as a staging ground for launching invasions into its neighbors. The delicate unity of Eolia's natives is frequently shattered as conflicting loyalties arise, alliances shift, and the troublesome elements eventually expunged.
People: Cassimis
Eolia has seen many exotic people come and go, but the cassimis have always been. None of the outsider species know precisely where they come from, but the smart money is that the perennially friendly doll girls are manufactured in the vast, impenetrable, featureless white quartz dome at Eolia's center. Whenever a new person comes to Eolia with a genuine intent to make the realm their home, a cassimi perfectly tailored to their deepest wishes will eventually appear at their location as if by magic and introduce themselves.
Cassimis take on some of the traits of their partners, but always have a humanoid figure, ball joints, a youthful and flawless appearance perfectly tailored to their partner's tastes, and an endlessly devoted and selfless demeanor. They are usually a head shorter than their masters, though not always. Aside from their devotion cassimi personalities vary widely but in general they are upbeat, positive, extroverted, impulsive, and not exceptionally intelligent, though even these generalities are subject to what would best compliment their owner. All cassimis have a tattoo somewhere on their body, typically someplace private, which functions as a combination barcode and keyhole. They come with only two accessories: a set of sheer, frilly white clothing; and an elaborate winding key unique to them.
The winding key is the literal key to cassimi existence. While they need not eat, sleep, or even breathe, they do require sustenance in the form of emotional energy. By placing the key into a cassimi's tattoo and focusing on projecting their emotions through it, a cassimi's owner imprints their wishes and desires into the doll. The cassimi is completely defenseless during this time, both physically and mentally. If not sufficiently relaxed the key will be difficult and painful to the cassimi to turn, and the effects of the emotional linkage unpredictable. A cassimi always knows where their key is and the fastest way to reach it, even across multiple realms. A cassimi can be wound with almost any key but not using their personal key will slowly drive them insane. Due to how important their personal key is to their wellbeing, it is considered the highest possible expression of trust in cassimi culture to allow their owners the responsibility of protecting it.
Beyond simply sustaining them, cassimis are capable of using stored emotional energy to achieve a wide variety of magical effects. As a baseline a cassimi with any emotional reserve to speak of is almost impossible to harm by non-magical means. More exotic effects than this are dependent on what sort of emotions they have been imprinted with. Anger can manifest as destructive streams of magical fire, fear as terrifying illusions, or love as protective wards. Cassimi emotion magic is always most effective and efficient when it fulfills the needs and desires that caused the emotions imprinted on them during winding, and least effective when it goes against the same. At maximum power, a single cassimi is theoretically capable of taking out an entire infantry company with armored support and emerging tired but unscathed.
In truth, all creatures entering Eolia have a tiny piece of their soul excised in order to create a cassimi. This operation can only be done once; if one's personal cassimi is lost or destroyed it can never be replaced. Likewise, if a cassimi's owner is lost or killed, its close connection to that being's soul makes it incredibly difficult or even impossible for it to ever connect to another person again. Cassimis who have lost their master often commit suicide, either sacrificing themselves in a storm of desperate vengeance to give some final meaning to their master's life or else simply quietly disappearing. Rarely, however, a cassimi can regain a reason to live by adopting someone important to their former owner as their new master. These heirloom cassimis are often a little mentally unstable and their loyalty much less unconditional, but they make up for it with superior experience and power.
No one knows exactly how cassimis function, even the doll girls themselves. Their bodies are animated by emotional energy, but without it they appear for all the world to be inanimate ball-joined dolls, indistinguishable from any other. On occasion a cassima will be broken open by violence or accident and something brilliantly alight in rainbow hues is seen within near the cassima's keyhole tattoo, but it is always vanishes without a trace a second later. While none know it, this is the cassimi's symphonic drive; a ludicrously advanced linkage of mirrors and polished crystals that acts as both brain and power source, the keyhole tattoo above it serving as its I/O port.
