Dal diario[]
- Sphera Mundi is divided into four Elemental Planes: the Plane of Earth, the Plane of Water, the Plane of Air and the Plane of Fire. Earth and Water together form our Planet, around which circulates Air. Above Air stretches the Aether – Fiery Air, or in short, Fire. Past Fire lie the Subtle Sidereal Heavens known collectively as Firmamentum, which are of a spherical nature. That is where the Erratica Sydera, drifting stars, and Fixa Sydera, fixed stars, reside.
- The Elemental Planes are inhabited by creatures which can be summoned by use of magic. They are: gnomes, sylphs, salamanders, and ondynates, all of which belong to the category commonly known as elementa ("elementum" in the singular).
