The Reset of 1811-1817 was a worldwide event

Energy weapons ere utilized

It put the nail in the coffin of the Tartarian Empire

It changed the climate
And froze the Northern Countries

It had:
Comets
Volcanoes
Earthquakes
Tsunamis
Liquefaction of the Terra Firma

It reduced the population 80%

The empty Tartarian Countries
Were then repopulated
With Underground Replacements!
