Drawing, as you can see, shows the messenger of the gods, who was sent to Earth to receive all states from people. The method is particularly devious-freeze all areas making it impossible to use. This allows the whole population of homo sapiens will die of starvation (yes, the gods of the people are horrible, vile creatures). On the planet will survive only cockroaches and mice. The lands will be given to them under the rule later.
I hope the description is clear (despite my poor English :) )
Advice in price :)
