ostentur

Ostentur is a fictional term that appears in certain speculative fiction contexts, particularly within tabletop role-playing games. It is not a recognized word in any established language or academic discipline. When it appears, ostentur typically refers to a type of creature or entity, often described as having ethereal or spectral qualities. Descriptions can vary widely, but common characteristics include invisibility, the ability to pass through solid objects, and a connection to a dimension or plane other than the material one. Some lore associates ostentur with psychic abilities or the manipulation of emotions, often inducing fear or disorientation in those who encounter them. The origins and exact nature of ostentur are usually left ambiguous within the fictional narratives they inhabit, allowing for adaptation by storytellers. The term itself does not have a widely accepted etymology, suggesting it is a neologism created for specific fictional worlds. Its primary function within these narratives is to introduce an element of the uncanny or the supernatural, serving as a challenge or mystery for protagonists.
