Fed by the eastern glacier system, the ocean is known for its fast moving currents that are vital for maintaining the Valaloth's normally temperate weather, even across the dry deserts. The significantly warmer waters along the Topoa's northern coast are responsible for the lush pockets of rainforest found there. But despite these beneficial effects, the wide temperature variance across the span of the Topoa can lead to some of the most violent hurricanes ever documented on a temperate planet. For this reason, even though Valaloth is generally a more desirable locale than the neighboring planets in the system, development and tourism along the coastal regions is severely restricted for several months out of its solar year.
It has been theorized that Valaloth was a wandering planet from a nearby system whose sun had burned out long ago. This reasoning came about from evidence that it is older than the system sun, G`lac Hurff. Astronomers suggest that the planet floated through space until G`lac Hurff caught it in its gravity field and took in Valaloth as one of the system's own.
Additionally, some researchers have propounded Valaloth's unique zoology as evidence for this theory as to the planet's origin -- its creatures bear no resemblance to those of the surrounding planets. To preserve the native diversity, there are laws banning importing or exporting creatures that are strictly enforced by customs forces at local spaceports.
