Super Volcano

A super volcano eruption causes a chain reaction of volcanoes all over the world to erupt as well as 2 new volcanic regions; Mae Volcanic and Raptor Volcanic. all macro life in the existing volcanic regions went extinct.


The massive amount of ash in the atmosphere blocked out the sunlight, causing much of the photosynthetic flora to die out. This causes a chain reaction of famine and starvation. In addition the lack of sunlight plunges Sagan 4 into an even deeper ice age. Informally known as the Snowball Event, almost the entire planet is covered in global glacier and only a few places at the equator stay warm enough to not freeze over. The ocean levels drop significantly until all that's left are two shallow seas. The geothermal vents in the middle of the seas keep them warm enough not to freeze. The sea salinity goes up, but most marine species are able to cope with it. Deeper ocean zones disappear due to the shallowness of the new seas. Over time the ash eventually clears and the sun returns. With the sunlight back the seeds and spores of the dead photosynthetic flora regrow. In addition the extra greenhouses gasses from the volcanoes tip the Sagan 4 enough to gradually get warmer.

Mason Dispersal

The massive eruption caused orbit voltflora to launch their seeds in mass, flooding the skies with seeds. Some of which landed on Sagan 4's moon, Mason. While the seeds died they did bring over a few microbes to Mason. Those that survived landed in Yokto Volcanic. Thus the followin species have migrated to Mason:
