Ryktah

Description
Ryktah is a planet 50 times the size of Gielinor but in the same solar system. It has a very strong gravity and the only organisms strong enough to live on this planet are the Rykth, a race of large orange beings. The planet is made entirely of red stone and has a very hot temperature.

Dangers
Ryktah's size and gravity makes it a threat to other planets in the system, because due to its gravity it can change the coarse of certain planets such as Gielinor itself, and cause a chain reaction of planetary collisions, which could destroy the solar system.
