Elementals
Salamanders: Mottled red and gray in color, these foot-long lizards have an eerie glow about them. Their skin is rough-looking, coarse and abrasive. Their eyes are black pits of coal in their ashen skin, they have no claws, and their teeth are flat.
These creatures have no need of teeth or claws, however; they breathe fire, and when aggravated, the skin, always burning to the touch, secretes a deadly, flammable acid. If the acid should come into contact with a patient's skin, the burning will be unbearable as a chemical burn begins to take place. As with all chemical burns, a base is required to stop the reaction. The skin will blister and then die where the acid touches, leaving a permanent scar behind. They keep to places filled with heat---warm places where machinery runs and fires burn.
Gnomes: Brown-skinned and misshapen, these small creatures are never found indoors. They favor the outside---places where they can burrow into the soil. They are vaguely humanoid, possessing four limbs and walking upright, but there all similarities end. They are blind, eyeless, and have no features other than a gaping, lipless mouth. Their skin is like leather, their hands are like a badger’s: long and flat-clawed to shovel through the earth. Or through something living.
Light immobilizes them.
Undines: Unlike the majority of monsters that inhabit the grounds of the hospital, undines are beautiful to look upon. Bearing the appearance of the mythical mermaid, these lovely women are blue skinned and white haired. Their eyes are like the ocean, the fishlike tails they possess instead of legs are silver and cobalt. They swim in the rivers and lakes beneath the hospital, and on some nights may even come to the courtyard pond. As enticing as these creatures are---and entice they do, with come-hither looks and sweet songs---beware. Their teeth are those of a moray eel, wicked and sharp. They feed on human flesh.
The voice of an undine is similar to that of the siren of legend, able to bewitch those to hear it into mindlessly drawing closer to the source. One so lured by the voice would see the undine as whatever being they would most want to see, whether that would be a lover, a mother, a friend, or simply someone in dire need of rescue. It requires a particularly strong will (or perhaps a complete lack of caring about other people) in order to resist the undine's song.
Sylphs: Sylphs, like the air, are everywhere, They favor no place above any other. These strange creatures are difficult to see, appearing as the outlines of small children. They look as though they’re outlined in clouds, white and brilliant. They can make themselves visible and invisible at will. But always they laugh, childlike giggles that never cease.
However, they are weak. Creatures of air, their bodies have little substance. They can steal the very air from a man’s lips, but they can do no other physical harm.
Tempests: The length of a man’s fingertips to elbow, these creatures could perhaps be called birds if a common comparison was needed. Long and slender and possessed of great stretching wings, their heads are perfectly round and sport no beak. In truth, their heads boast no definition save for two giant, pure white eyes. Their limbs are two small legs, ending in three rounded knobs and extending out from the middle of their serpentine bodies. Their flesh itself is a dull metallic blue, scabbed and scarred in grotesque patterns. Their wings are feathered and a tarnished silver in shade, and end in two gleaming metallic rounds. They reek of sulfur and ozone. While they have no teeth or claws, they possess the ability to arc their wings and produce lightning itself, conducting the elemental weapon with their bodies and shooting it at their prey. Alternatively, they can pack the electricity in their body and deliver a direct shock that is far more painful - like getting knocked back from an electrical fence.
Phantasms: Phantasms are creatures made up of the utter absence of light, a darkness more profound than the depths of hell. They are shapeless and formless, only visible as a lack, an empty space silhouetted against light. They move as shadows move and seek only to suck the light and warmth from the living, for where they go hopelessness and desolation follow.
A phantasm is nothing but a void that seeks eternally to be filled, though it seeks always in vain. Their touch does not bring despair or sorrow, for that would be creating something; instead it simply drains away all emotion, thought, hope, or even will to live. They leave behind an utter apathy, an emptiness of spirit deeper than even the phantasm's darkness.
Simply being near a phantasm (roughly ten feet away) can drain away warmth and emotion, leaving a room cold and unpleasant by its mere presence, but the effects will vanish as soon as one steps away from its immediate range. As soon as the victim comes into contact with a phantasm they immediately become cold and their will is drained; this can be dangerous to anyone traveling alone, as they will lack the energy to move away (though if someone is walking through a phantasm the momentum might carry them through, for instance). The longer the victim is in contact with a phantasm the longer the effects will linger: the effects of a brief touch will fade within a few minutes, but seconds or minutes more will cause the effects to linger exponentially longer. Should a victim stay in contact with a phantasm for 7-10 minutes (depending on the victim's strength of will) they will come to lack even the energy to breathe or keep their heart beating.
Phantasms cannot be killed or injured, but they can be driven away.
Lucentiens: The opposites of phantasms, solid - so solid their flesh is almost impossible to penetrate - and bright, glowing with a strange dull light the seems contained to their body. They cast no light on the floor or walls about them. They are humanoid yet lack any human definition - a trait that seems common among the humanoid creatures of the hospital. They are like mannequins, moving jerkily and with deathly precision. They are sexless, toothless and blind, their skin almost gold in color. Their nails are like blades, double edged swords that extend from each of their four thick fingers. Their skin is metallic, the only place a blade my pass through is one place upon their smooth backs. It is from there and there alone that they bleed. And the blood of the lucentiens carries with it a mysterious power….
