Basic Information
Anatomy
Oni are among the tallest of the mortal species, often standing between 6’5” and 7’6”. Their bodies are heavily muscled, with dense bone structure and great endurance. Oni skin tones range across vibrant hues of red, blue, or yellow, setting them apart from most other species. From their foreheads grow distinctive horns ranging from one to three per individual which may be straight, curved, or spiral in shape. Hair is typically coarse and dark, though brighter colors sometimes manifest in magically gifted lineages.
Biological Traits

- Elderhood (251–300 years): Though slower in movement, elder oni remain formidable. They are valued for their wisdom, artistry, and mastery of martial philosophy.
Ecology and Habitats
Oni thrive in mountain ranges and colder climates, their naturally higher body temperature protecting them from harsh conditions. Villages are often built into cliffsides or carved into stone, combining fortifications with communal halls for feasting, training, and artistry.

- Artistry: Many oni are accomplished smiths, carvers, or musicians, channeling their emotions into creative works.
- Combat Philosophy: Oni believe that combat reveals the truest form of self. In battle, they seek not only victory but also understanding of their own spirit.
