One of the strangest theories of the whole universe I found on this cultured world of Ploid. They divide time into three general periods of ages:

3. Age of Ice.

This age, they claim, was followed by the Temperate Age, or the age in which they are now living.

It is also claimed that, when their earth cools and the frigid blasts freeze out the world, there will gradually commence the Age of Ice, or the age in which human species will exist by reason of the earth's stiff coldness.
