Cosmology

The world of Avlis uses the cosmology set forth in Advanced Dungeons & Dragons Second Edition for determining the nature of planets, stars, and space. According to this model, each star and all of its orbiting objects are enclosed by a Crystal Sphere many times the diameter of the star. The distance from the star to the furthest orbiting object is usually the same as the distance from the furthest orbiting object to the wall of the Crystal Sphere. The objects in the night sky that groundlings call stars are in fact holes in the Crystal Sphere which permit a properly-equipped space-faring ship to exit through them. "Spelljamming" is the term used to describe magical flight through space and beyond. An alternative term that does not violate copyright rules for Wizards of The Coast is "Starjamming".

Outside of the Crystal Sphere is a translucent ether substance called "phlogiston" in which the Crystal Sphere floats. The "Phlogiston Flow" is the area outside of The Crystal Sphere that shines with about half the amount of light on a normal day. Phlogiston as a substance is highly flammable and can ignite with the slightest spark causing damage to a vessel and its crew.

Daggerspace

The Crystal Sphere which contains Avlis and its fellow worlds is called Daggerspace. Tradition holds that Crystal Spheres generally originate from the actions of rare beings which wind up taking variable amounts of care and supervision for their creations. The being that created Daggerspace has no formal name but writings refer to it as The Supreme. Within this being's Crystal Sphere, there are numerous celestial bodies of which many remain undiscovered.

Celestial bodies come in all shapes, sizes, and natures but generally break down into only a few types: the sun, planets, moons, and asteroids.

The Sun

The sun is the largest celestial body in Daggerspace. It acts as the focal point around which all celestial bodies orbit in a circular fashion. There are many other suns (or stars) in other Crystal Spheres of different sizes and natures, but the sun in Daggerspace is about 700,000 miles in diameter an composed of a mixture of fire and positive plane energy.

By its nature, the sun is mostly made of gas and has no uniform surface. However, there are numerous portals within it that lead to the Elemental Plane of Fire, the Quasi-elemental Plane of Radiance, and the Positive Material Plane.
