30000 years ago humanity got attacked by otherworldly beings, these fantasy beings we usually read in fantasy books are actually all real, they come in great numbers through dimension tunnels and attack everything without care, at first we try to rely on our advanced weaponry like guns and missiles to fight back, some countries actually opted to send nuclear to bomb an entire city, after 1000 years of fighting back our ammunition run out our supplies running low and earth starting to change, at first an EMP like burst start coming out of the dimensional tunnels all around the world crippling most of our technologies, unable to contact each other for help we started getting swarmed by these fantasy beings and finally Mythical beings like Dragons and Phoenixes pop out of the dimensional tunnels, we Humanity have no choice but to dig down the earth and live in the "Darkness",
Fortunately we found things inside the earth that just might help us survive.
My name is D and i am one of the survivor that lives in the Darkness.
