One of a trio of gas giants found within the Brentaal system, Gumbus is an immense world which engages in a sort of stellar ballet with its sister world of Gastol, both partnered to their sun in their dance through space. As the slightly larger of the two worlds, Gumbus has received rather much more of the attention, with both science and corporate exploratory missions skimming through the thin clouds of the upper atmosphere and dropping sounding probes to chart the lower reaches. One of the most interesting pieces of meteorology in the entire Bormea sector, the winds of Gumbus have been the subject of entire research projects in and of themselves. Close enough to its star to become tidally locked to some degree, the wind storms are a sight to behold from orbit, with the sunward side constantly churning with powerful counter-spinning storms clashing across the visible surface. On the other side of the planet is a much different seeming world, with slow eddies gradually flowing in wide, lazy bands.

Despite the presence of large colonies, several governments have used the world as a training ground for their atmospheric and trans-atmospheric pilot programs. The sunward side has enough turbulence that it can give even veteran pilots pause, and for those who are destined to dive groundward in the worst and most hostile environments, The Intermix stands between the cold and hot halves of Gumbus. Tossed by supersonic winds, violently mixing high and low-pressure zones, and terawatt scale lightning storms, this zone is made exceptionally obvious due to sharing its location with the solar terminator, where the light and dark sides meet. Very few organizations still use this zone for training missions, as those attempting the feat of flying within it have experienced horrendous casualty rates. Of those who have survived though, not a single member has ever been killed by a natural hazard, such is the skill making it through this region imparts.
