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. In some instances, floating rocks traveling through these other planes can sometimes fall through portals into Daggerspace accidentally and remain floating within the sun. Though it is rare for this to happen, there are at least several floating molten rocks within the sun.

Temperatures inside the sun are as hot as the Elemental Plane of Fire. Conditions inside the sun are a simultaneous combination of ambient conditions within the Positive Material Plane and the Elemental Plane of Fire, which means that it is hot enough to melt nearly anything without magical protection, but the atmosphere is breathable if the other dangers are mitigated. Positive Plane Energy conditions within the sun actually cause superior spontaneous healing in all biological matter, which combined with the burning of the elemental fire would bring about exquisite torture to any being caught unprotected within it for a short time before it explodes.

Planets

Daggerspace has several inhabitable planets. Scholars are not sure if they have yet detected them all.

Tairis'Nadur

The planet of Tairis'Nadur is a small inhabitable world with oceans, landmasses, and civilizations all its own. It is the innermost known planet in Daggerspace. This planet exists as a linked server for the Neverwinter Nights game that is part of the Confederation of Planes and Planets.
