A General Overview of the Fear-its
 
The "Fear-its" have long been known by the barbaric arctic culture; 
their true name is "Vacalids", coming from a realm known as Vacalidia.  
The nature of these Vacalidians is simple:  they are dead.  In general, 
one may recognize a Vacalid by their pale, sometimes rotting flesh, but 
mostly by their vacant, empty eyes (there are exceptions).
 
I haven't pieced together the entire history of this bizarre people, but 
it seems that most of them are available for summoning by casters who 
know the proper rituals.  They live in a separate plain, where they 
live in a sort of "community", waiting for summoning.

The Undead Vacalids
 
In actuality, all of the Vacalids may be considered "undead" as they are 
the living dead, however I am suspect of the true nature of some of the 
higher beings, and others fit better under other categories.
 
In any case, the undead comprise the majority of the Vacalids.  These 
include such things as walking corpses (zombies), vampires, mummies, 
etc.  All of these I have encountered display the "blank eye" symptom, 
that of lifeless, soulless bodies.  Most of these can be very dangerous, 
carrying disease and also a ferocious tenacity in combat!

The Elemental Vacalids
 
The elemental vacalids form an interesting lot.  They are very similar 
to the elementals which can be summoned through the 'summon elemental' 
spell, however they tend to be less corporeal.  I have noticed that they 
spend a lot of time in their 'natural' form, although they do revert to 
a humanoid form occasionally.  
 
Fire elementals can hide inside a fire, giving a good attack advantage, 
and air elementals can hide as a faint breeze, coalescing to attack, 
etc.  These elementals tend to display the same 'blank gaze' as their 
other compatriots.

Spirit Vacalids
 
I have discovered that the spirits (or 'ghosts') of people may become 
'fear-its' through certain ways.  Either through ritual preparation of 
the dead, or if one happens to die in their realm, the soul cannot 
escape and it becomes trapped there and transformed to Vacalidian nature.
 
The spirits may retain basic emotional states of their former lives, but 
other than that, they retain no memories.  The spirits will usually 
display a temperment based on the most prevelant of emotions of the 
former being, such as hate, love, sadness, etc.  These too display the 
vacant darkness in the eyes.

Dread Beings
 
I have only seen one in my experiements, and it was indeed dread!  In 
fact, I could barely contain it with in my summoning circle, so great 
was its power.  
 
It seems that the Vacalids have a semi-ordered structure (I say 
semi-ordered because there can be vying for positions through violence, 
so things continually change) in which the more Dread creatures attain a 
higher position.
 
These creatures display the same vacant black-eye gaze, but they each 
have something distinct and unusual about them.  The one I came into 
contact with gained power from absorbing the light in the room!  Truly 
these beings are very dangerous.

The Unspeakables
 
I have, in my conjurings, heard rumors of the next to highest ranked 
beings, but noone will speak about them, thus I have termed them "the 
Unspeakables".  All I can tell about these beings, is that there are 
three of them (sometimes referred to as "the Three") and that they have 
always retained their current position.  Also I can discern that these 
support some sort of 'supreme' being (which see).  
 
I have no physical data to present on these elusive beings.

The Supreme One
 
This creature is talked about even less than the Unspeakables.  In fact, 
I have only heard mention of him twice.  One by a Dread being, and 
another time by a much lower minion, which summarily disintegrated.  I 
have vague referrence that he is somehow linked to the Three, but the 
exact nature of this relation is unclear.  However, due to the great 
power of the Dread beings, and the supposed greater power of the Three, 
I must assume that the Supreme One indeed deserves the title!
