Viral is the name of a highly-populated world in the D-Verse that serves as the setting for most of the Steampunk arc.
Viral is a smaller and hotter planet than Terra, with large expanses of desert and barren areas as well as a mineral-rich crust. The planet's main continents are near the equator, while the poles are dominated by oceans ringed with large islands. Each pole is also capped with a single perpetually frozen area due to buried artifacts maintaining the temperature. Overall, only a third of the Viralian surface is water-covered.
