Year 2019

For several years, large-scale crust sinkage, disruptions in ocean currents and other abnormalities have been reported in regions throughout the world. Various theories were expounded by the international community of experts, but none of them were even close to generating a solution. However, there were two people in the world who sensed the cause of these anomalies.

Their names were Roddy and Ellfie: Jason's children, who had been left fatherless too soon and too young by Jason's untimely death. The first step must be to confirm their suspicions...

Roddy takes the newest model Sophia, once his father's, deep underground... Soon they saw the second crust Jason spoke of in that land below land, and a gate-like structure from which issued a number of strange creatures.

...that just like in the past described by the children's father, they had begun their move towards the planet's core.
