Jewel is the first planet ever colonized by the Imperium and is well=regarded as a tropical paradise. Ninety percent of Jewel’s surface is covered in water and there’s very few large landmasses. Instead, most of Jewel is dotted with islands in large archipelagos.
Jewel was originally founded by Emperor Karr himself as a secret base during the Mage Wars. In fact, historians (especially those that reside on Jewel) would argue that the planet was key to the Emperor’s victory in the war.
In modern times, Jewel is primarily a vacation planet since there’s not enough land to support a large population. Pleasure cruises in giant ships are a popular choice for those wealthy enough. Besides tourism, Jewel also has a thriving fishing industry and some of the most expensive sea food delicacies come from its oceans.
