Sun

The sun is the center of this realm's "Universe" and has many satellites including planets and nebula. According to the Astronomia Praesidium Societatis it is a direct portal to the Elemental Plane of Fire and holds something very evil at bay.   Unique Feature: it is a dragon "god" from another dimension resting to gain its strength.  

Notes

A sun that is linked to the Plane of Fire The Sun, also known as Sol, is the primary of the crystal sphere known as Realmspace. It is a size H spherical fire body, and is orbited by 12 planets, their satellites, and a variety of asteroids, comets, and nebulae. Within the Sun's immediate orbit there are twelve sargassos.  

Overview

The Sun is located at the exact center of the crystal sphere, and as such is considered the system primary of Realmspace. The fire body burns with such fury that it maintains the whole crystal sphere at an unusually warm temperature. Many sages believe that the older a crystal sphere is, the warmer its system will be. If this is true, it means that Realmspace is the oldest crystal sphere encountered thus far.   The Sun, when viewed safely, is a seething ball of fire. The surface is covered with lakes of molten earth and liquid flame, kept burning by the mass of, and friction created by, the sheer bulk of the sun. This causes the hydrogen atmosphere to erupt in flames that spiral out for millions of miles in enormous columns of fire known as solar flares.   The climate of the sun is one of eternal heat. The temperature is such that it easily overloads any protective magical spell or item within seconds, instantly killing the user. Occasionally, the sun will experience cool zones, which appear as dark splotches on the surface of the sun. Known as sunspots, these relatively cool areas are still incredibly hot; hot enough to negate any protection offered by any known magical device. This has ensured that the sun has yet to be explored or exploited by any of the civilizations of the system.   The Sun has many layers, starting inside is the core -- a gigantic planet-sized primordial Dragon "God" from some other plane or universe. Surrounding him are many layers of various magics and portions of other "Planes". Finally, there is a thick layer of the Plane of Fire which exists in both places, to finally become the top layer -- as described above  

Features

The sun's surface was made up of varying areas of molten earth and fluid flame, a distinction which only was useful for its fire-loving inhabitants. Some areas called sunspots were somewhat cooler than their surroundings and could be recognized by their darker color. At other places, pillars and loops of flame could violently spurt outward from the sun's surface for millions of miles.   The surface also featured hundreds of portals to the Elemental Plane of Fire, allowing access to the natives of that place.   Another dreaded feature could be found 40 million miles (64 million km) away from the sun: like balls on the spokes of a wheel, twelve spherical dead-magic zones with a diameter of 100,000 miles (160,000 km) each orbited Realmspace's central body. They were called the sargassos and were feared by every spelljammer crew, which depended on magic for movement after all.  

Inhabitants

The surface of the sun is dotted by hundreds of small portals to the Elemental Plane of Fire, which allow various fire elementals and other fire-loving creatures to make their homes on this stellar object. Many of these creatures are relatively well known, such as the efreeti, firenewts, salamanders, and fire minions. Other less well-known creatures also make their homes here, including lavaworms and helians. The creatures that live on the sun appear to be able to return to their native planes, but they all seem to prefer the sun to their original homes.   The sun was inhabited by many creatures originally native to the Elemental Plane of Fire: efreet, fire elementals, firenewts, fire minions, helians, lavaworms, and salamanders had been recognized. It has also been surmised that inhabitants of other fiery places on the planes made their home there.   Only a few attempts by the sun's denizens to leave their home have been registered, but any spelljamming ship that got close to the sun was violently attacked by them, especially the helians.  

Trade

Unfortunately, there has been no reliable way of communicating with the sun’s inhabitants. Additionally, whenever a spelljamming vessel gets within ten million miles (16 million kilometers) of the sun and survives, the inhabitants react with hostility and attack the vessel. There have been many documented accounts of helians riding a solar flare from the sun's surface and throwing burning fragments of intense nuclear heat at all ships passing within range.   However, it is believed that some of the more intelligent elemental creatures living on the sun are aware of spelljamming technology. There have been several reported cases of spelljamming vessels made entirely out of flames. There is even a documented case from a reliable source who reported that such a ship had departed from the sun. Unfortunately, the flames of the ship had died long before the vessel could reach the orbit of Anadia.   Since there has only been one reported case from a reliable source, it is believed that the sun’s inhabitants either have no desire to exploit this particular mode of transportation or that they view spelljamming as being too unreliable. Since the Elemental Plane of Fire is as broad and expansive as the prime material, there is still much that requires exploration.  

History

The wildspace of the Realmspace crystal sphere was unusually warm compared to others. This led sages to speculate that the sun and Realmspace itself were the oldest among the generally known crystal spheres.   It was believed by sages and priests that the sun was created when the goddess Chauntea begged for a source of warmth, so that she could sustain the life flowering on Toril. The goddess Selûne ignited one of the heavenly bodies floating in Realmspace with pure flame from the Elemental Plane of Fire, creating the sun. This act started the enmity between Selûne and Shar that had lasted ever since.   According to old sarrukh legends and Abeiran traditions, during the cosmic cataclysm known as the Dawn War, the primordial known as Dendar the Night Serpent devoured the sun, starting the time period known as the Shadow Epoch. It was believed that a new sun was created to support life after the war was over.  

Portfolio

Among the deities, Amaunator took responsibility for the sun within the Faerûnian pantheon; first Re and then Horus-Re in the Mulhorandi pantheon; and Utu within the Untheric pantheon. In the Maztican pantheon, the sun lay in the domain of Tezca. In Kara-Tur, it was believed that the Moon Women of the Celestial Bureaucracy were responsible for refilling the great oil lamps that made the Sun shine, while there was also a Spirit of the Sun among the many deities of Wa. Among the giant gods, Stronmaus had the sun within his portfolio.     Climate: is one of eternal heat. There is no known magical item that will enable a creature from the Prime Material to survive here.   Prominent Land Features: The Sun does have certain features, but they are completely unusable to the standard character races.
