H'Catha

H'Catha was the eighth and farthest planet from the Sun in Toril's solar system, also known as Realmspace. Seen from Toril, it appeared as a crystalline glimmer of diamond white, although sometimes it was reported to appear as an emerald green star. . It was the last of the Five Wanderers, the five superior planets of the Torilian solar system.

Geography
The planet consisted of a flat disc of 300-mile thick water with a single mountain in the center. Close-up, this world looked like a giant wagon wheel, with the mountain, known as the Spindle, always pointing directly at the Sun. Over 1,000 miles (1,600 km) tall and 200 miles (322 km) wide at its base, the Spindle was the tallest mountain in all of Realmspace.

Because of the planet's distance from the Sun and the fact that its rotation kept it always facing the sun, H'Catha's climate was cool, with the temperature always at 50 °F (10 °C).

H'Catha had two moons that orbited the planet at its equator.

History
H'Catha was originally inhabited by a culture that had lost three ships trying to prove that their world was round. After the planet was taken over by beholders, the fate of this civilization was unknown.

Inhabitants
Near the base of the mountain, six ports, each owned by a different type of beholder, accepted spelljamming traffic from other beholders, (not ones who lived on H'Catha, as that would provoke a war,) and a mysterious humanoid race. Other species were only allowed to land if they had goods to trade and left as soon as they were done. The world was orbited by two satellites, Turnbetl and Lumbe.
