Nonexistent
The outward appearance of nonexistents is mostly that of empty clothes, armor, or cloaks, wandering alone as knights, paladins, thieves, sorcerers, and so on. To avoid upsetting the populace, they are careful to cover themselves up so that the void under their capes or mantels is concealed. They manage to speak normally by using ventriloquism of some sort, walk and move like ordinary people, and perceive the surrounding world through senses similar to human ones. When their garments are removed or destroyed, nonexistents are simply not there anymore, and can no longer interact with the earthly world, not even by magical means.

Although the first nonexistents mentioned in ballads and tales were knights of noble mind and irreproachable morals, these beings can manifest any alignment, personality, emotion, instinct, thought, or state of mind, with one main difference compared to more common beings: they always demonstrate their will, ideals, and intentions in a heartfelt, almost urgent manner, as if they were made of pure sentiment.

So far, no recognizable differences of sex, gender, or race are known to exist among the nonexistents. They are totally self-determined and use the tone of voice and attitude they deem most appropriate.

How Other Races See Them
The true nature of nonexistents has long been the subject of speculation, including the significant opinion that they really aren’t anything at all. Some believe they are invisible beings; others, animated armor or clothing; still others, a particular type of ghost; finally, there are those who consider them an ancient accursed lineage; however, scientific observation and conversations with these beings would seem to disprove such theories. The most widespread thesis today is that they are “abstract intentions” that have acquired the power to manipulate objects around them and to move in the earthly world. Given their utterly mysterious, and possibly sacred, diabolical, or magical nature, they are generally treated with respect or deference, but also with detachment, by all other beings. Who knows what intentions they really harbor under their disguises?
