Coliar

Coliar was the second planet from the Sun in Realmspace. Seen from Toril, it looked like a gray and white orb which never appeared too far from the Sun. Coliar and Anadia, the two inner planets of the Torilian solar system, were known as the Dawn Heralds.

Geography
Coliar was a gas giant enveloped by a 100-mile (160 km) thick layer of clouds. Below this cloud cover, the entirety of the planet was transparent air and occasional clouds, dotted with countless floating islands that orbited the planet's center of gravity at vastly different altitudes.

The islands varied in size, ranging from 5 ft (1.5 m) to over 20 miles (32 km) in extension, and were all uniquely shaped. The islands contained every land feature expected from land formations, such as lakes, rivers, hills, grass, trees, and caves. Because they orbited the planet's center from different altitudes, eclipses were common throughout Coliar.

Coliar was a generally warm planet, due to its proximity to the Sun. Rainstorms happened periodically on the planet, during which lightning struck the higher islands more often than the deeper ones. For that reason, the aarakocra inhabitants preferred to live on the deeper islands.

Trade
The main export of Coliar was its air. However, air was a difficult commodity to sell because most spelljammer ships usually just stole what air they needed.

The aarakocra inhabitants also mined gems from the inner islands and exported them in exchange for weapons, which they used in their territorial disputes against the lizardfolk.

The lizardfolk, on the other hand, exported aarakocra meat and feathers, as well as gems, air, and water, in exchange for spelljamming technology, which they used to power ships that would carry their eggs to be hatched closer to the The sun. In order to enforce the purchasing of air and water, lizardfolk ports charged an air tax to any ships that docked at them.

The dragon inhabitants mostly ignored ships, unless provoked.

Notable Locations
At the center of the planet was a very large island, inhabited by the red dragon wyrm Firebrand Flametongue. Very few people were allowed to approach the central island without being attacked by the dragon.

Close to the center floated Elminster's Hideout, a metallic spherical island about 250 ft (76 m) in diameter. It served as a hideout to Elminster Aumar.
