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
A PC Conjurer or summoner, basically any mage whose sole purpose in life is summoning creatures to aid in battles and various situations, is cursed with a hex, and needs to find a way to undo the curse...before he goes mad, or his fellow PCs throw him out of the party, or worse.
Everything he/she summons, never goes away. So you'll have to figure out what the heck to do with that dire bear or fire elemental once it's done fighting the orcs for you. Eventually a caravan of bizarre creatures either annoyingly ends up following the summoner around, or they go off to cause mayhem elsewhere. Bad news for the poor spell-caster regardless.
