This area has heavy volcanic activity. Several smaller eruptions per week are not uncommon, and Meneb experiences regular earthquakes and tremors. The volcanoes in this area constantly vent toxic gasses -- While this is devastating to the natural flora and fauna of the area, the gasses also have magical properties. Several refineries have been setup to filter the gasses as needed, and you can find the refined magic in many everyday products, such as potions and elixirs.
The climate of Meneb could easily be described as muggy and undesirable. The constant heat of the volcanoes, combined with a layer of ash-cloud working as insulation, makes for a sweltering daily average temperature.
