Zryggheympe (also known as Planet Nitro 015) is a Planet Trade Organization-controlled world. It is in Lord Nitro's territory.


Zryggheympe was home to two sentient species, the Savil and the Ocarans. For many years, the Savil suppressed the Ocarans and built vast, splendid cities. However, their greed and neglect proved to be their downfall. After years of being treated as animals, the Ocarans staged a remarkable planet-wide massacre of the other race. The Ocarans were brutal and savage, and soon they completely eradicated the Savil. Thereafter, they lived in the Savil cities. Ocarans were not advanced enough to create their own cities, so they could not maintain the Savil ones. Soon, they fell into ruin and the Ocarans returned to their swamps and hovels. The planet remained in its natural state thereafter. Of course, Nitro soon found the Ocarans, and he enslaved them to his side. He took most of the Ocarans off of the planet, deciding to put them into breeding facilities on other worlds. This rapidly depopulated their homeworld. After the collapse of the Planet Trade Organization, this planet was left untouched by the wars. Since the native Ocarans were not space-faring, they were not major players in the war.

Zryggheympe itself is a world filled with toxic swamps. The entire planet is filled with trees and bogs, and there aren't any true oceans or dry lands on the entire planet. The planet goes through long seasons of rain, but other than that, it does not have much in the way of climate. The regions near the poles are slightly colder than the area near the equator, but the difference is insignificant overall.

In Age 749, Fassfu, Kaesh, and Chaiva were deployed to the planet to repel a group of reaving space pirates. They were successful in wiping out all of the pirates, though several outposts were damaged and thousands of natives and soldiers were killed.
