This is on a species not a character this time
They reside within the realm known as the void
The void is before and after existence - take that as you will
Voidlings within the void take the form of a shapeless mass of ooze and eyes gleaming in the eternal darkness
However voidlings are able to take a more physical form to allow them to more directly interact with others outside this realm
1. A ritual done properly - using a special ceramic like material to be the object the voidling is bound to - these ones are the most human in appearance although if their 'mask' is damaged their appearance will deteriorate
2. A ritual done inproperly - using things other than the specific material required - these appear still humanoid but often have too many limbs or sharp claws
3. A ritual but unwillingly - some voidlings do not desire to be physical and prefer their more hivemind like state so if forced into being whether properly or improperly the 'mask' will break beyond what is usually sustainable for a voidling(.i.e entire pieces breaking off) and trap them more permanently (though they can be returned through a separate ritual) - these ones often cover their bodies from the 'neck' down as they dislike their reminder of their separation
4. Voidlings who become physical through shear force of will - their desire to be 'real' allows them to claw their way through the barriers between realms (Eskitar spends a lot of time fixing this) and attach themselves to whatever objects they can find (often younger voidlings who take this path) - generaly smaller than standard (though this may simply be due to their age) often spindlier or with stubbier limbs than their counterparts
While physical, if their 'mask' sustains excessive damage (with a few exceptions) they will be forced to return to the void
They are a generally curious species, especially the younger ones
Can be grumpy and/or dislike other non-voidlings
Eyes are very important in their culture
Few are actually able to speak languages understandable to us
They often speak overlappingly and contradictingly
