Generation 125

Disaster (Ice Comet) An ice comet crashes into the Jujubee Ocean and widens the Otter Vents. This causes worldwide earthquakes, volcanic eruptions and sea level rise. All cave-ins collapse and new sea caves form at the new sea level from old caves. All macro life in the volcanic caves have become extinct due to their super eruptions. The continuous earthquakes cause avalanches and thus rivers to flood and even expand in the case BioCat River. The smoke from the volcanic eruptions block out the sun for a long time and thus all species one meter or larger on  land, down in the sea, underground and above in the air become extinct. Not only is the geography of Sagan 4 changed forever but the small species that survive will change the face of Sagan 4 forever.
