Every 10,000 years this event takes place, the crusade dragon ... the ancient peoples who had colonized the planet long before the birth of humanity called the "beginning of a new era" we can call it "APOCALYPSE"
In this event, Mesmyriza decides it's time to give chance to new forms of life to be born and to colonize the planet, as we humans, so maximizing her size, simply starts to walk around the planet by destroying all forms of civilization and the total extermination of humanity ... so bringing the planet "stone age"

The only thing that will be able to give us a bit of relief to think that we will all be swept away by her feet :D
