Ellis IV was the first world settled in the system and it remains the most populated planet. It is also the only planet in the Ellis System with an economy that revolves around anything but racing.
Kampos is a high-gravity ocean world stocked with all manner of sealife. The planet itself is named after a particularly large sea creature (though not one of the many whose harvested meat is available for export). Kampos’ high gravity also gave rise to the evolution of flatcats, which formed the basis of a brief fad in the UEE core worlds. The world is frequently called Seahorse by the locals, so-named for the appearance of some of the high-gravity sea monsters harvested by native fishermen.
