Radiocene, formerly 'Origin of Kaiju', is an ongoing  speculative evolution and worldbuilding project of mine focused on reimagining monsters seen in both the Godzilla and King Kong franchises in a biologically plausible manner.

This project takes place on an alternate Earth biosphere very similar to our own with all but a few major deviations. The most notable feature of this world is the presence of increased geological activity - which has resulted in the formation of complex, interconnected cave systems, called the Hollow Earth Tunnels (HET), that shield numerous species from the dangers of the outside world, creating an entirely unique and vast underground ecosystem in the process. 

The same processes that formed the HET are also responsible for the upbringing of radionuclides into the top layers of Earth. The presence of this radioactive material in the upper crust has most remarkably resulted in various plant species becoming radiotrophic,  capable of thriving even in the darkness of the Hollow Earth Tunnels. 

I will begin posting my work in here soon, stay tuned and thanks for reading!
