Cycle - Period of intense climate conditions, including earthquakes, volcanic eruptions, acidic rain, dust walls, and raining spikes (floating plants that wither in the harsh conditions, then when the weather is better, they sprout again and make the journey back to the sky where the nutrients are thickest and the air thinnest). The planet is in this condition for much of the time each year, and it is the period when the heavens need to migrate until the climate changes pass.

Transitions - Short periods between cycles where the climate is hospitable for landing and maintenance. Landing pads are located around the planet and were created by each civilization in an effort to unify their common goal of survival.

Underworld - The crusted over ruins of colonies that attempted to keep living on the surface after the catastrophe changed the face of the planet. These cities had built walls all around the city (like a dome)  that protected them for a time. When the cycles would come, it would slowly destroy the cities from the inside and oustide. The earthquakes destroyed the inner city, while the constant volcanic river flows would surround the walls of the city. During each transitional period the lava would harden, and while the people tried to cut it away from the walls at first, the cycles began increasing in intensity and frequency to the point where the cityies were literally buried alive.
