A relentless and unearthly durable type of dimensional fatigue 'denizen'
The first documented virtual illness.
A mutation of Legionnaire's Disease, Space Sickness, or Space Lung, is a not uncommon malady of the Cosmic Era
There will come a day when mankind discovers the means to leave his solar system, to strike out into the galaxy and the myriad of stars and worlds beyond his own. There will come a great and terrible shock, because beyond that safe border, the galaxy is bright, and full of monsters
Strange things can be found in deep space, well away from the gravity and nuclear fury of a living star
Plasmid and plasmic lifeforms are frequently relegated to the back bench of the creature roster, left to linger with oozes, slimes, and puddings, and only appear as random monsters in sci-fi.
Each time mankind ventures into a new realm of exploration, he returns with tales of incredible creatures. Be it from the new continent, the tops of the mountains, or the depths of the seas. It is the acme of foolishness to assume that space would be empty of lifeforms. The forms that these new biologies took simply defied conventional physics or chemistry
It's always the creepy little kids
Also known as Kaiju Spawn, Magna-parasites, angel-spawn, sin spawn, and a variety of other terms
Methinks we have hugely mistaken this matter of Life and Death. Methinks that what they call my shadow here on earth is my true substance. Methinks that in looking at things spiritual, we are too much like oysters observing the sun through the water, and thinking that thick water the thinnest of air. Me thinks my body is but the lees of my better being. In fact take my body who will, take it I say, it is not me.”
A strange mask containing a merciless demon, a parasite on those around it.
They came upon us suddenly, no sound preceding them until the splashing of their feet drew our eyes towards them. The wolf-things neither howled or snarled as they tore into our ranks.
At one time it was thought that the substance known as Anagra Estratius, or Devouring Fire, was an alchemical substance, tainted by the infernal components that went into its making.

When we learned of these majestic creatures, what else could we do? Such potential!
A haunting remnant of the infernal realm, caught and exiled to suffer for eternity in the swamps of the mortal plane. Now it toys with mortals; luring them from their paths into it's light. Once in the boundaries of it's aura, the FlickerWikk will feed.
A Remake of the Will'o'the'Wisp/Jack'o'Lantern
Rumors of gold and more, spoken on the wind draw the greedy to their doom.
Damn 'ol thing it tis. Itches like nuthin I e'er felt. Stupid bugs, your the Poosker ye fool. Help me get rid o' these damnable things.
I hate to tell you this but you have what we liked to call, "Puces Barbe Morts", or undead beard fleas. And the only way to be rid of them is to cut off your beard and then burn the hair.
No! Just kill me it's less painful that way.
A very brief look at some minor Elemental familiars.
A extra-dimensional symbiote
In nature, for instance, a rhino has flies and ticks etc, that live on the hide and live off the blood. Rhino will visit and lie in ponds where turtles will clean the underwater portion of the ticks and a species of bird will clean the the top of ticks and other parasites. What if where the characters camp there were a species of animals that lived off wounds of the creatures. PCs camp. Anybody with wounds on there body are soon covered with small rodent - insect - shadows - whatever. Would immediately see it as a threat I would imagine. But perhaps one of the wounded didn't wake up when it happened, and when they did finally wake they were completely healed. Perhaps somebody was warned of something attacking them but they were able to notice that the wound was actually getting smaller instead of larger. Or maybe they successfully beat the creatures off them and don't notice an improvement, marking this place never to rest at ever again....later learn that villagers send their wounded there but they keep it a guarded secret because they don't want all the attention or traffic and what comes with such a special gift. Could turn into something more too if characters decide to start blabbing about it.
