Raid TCG takes place on the planet Thalos. This planet is located at the exact place in the space-time continuum as the earth. The two planets are from different universes, that are aligned perfectly on just 1 place. A mysterious cave connects the two planets.

This cave was discovered first on Thalos hundreds of years ago. The creatures from Thalos protected the cave and learned very rapidly about Earth. Our planet served as a library filled with knowledge for many species on Thalos. These species would learn from the mistakes and triumphs of the mighty human.

Studying Earth started a massive technological revolution on some parts of Thalos, wile most of it is still relentless nature.

For hundreds of years the species on Thalos knew about the cave that leads to Earth, but kept this as discreet as they could towards humanity. No matter how hard some species of Thalos tried to hide the cave, not all species had the brain capacity to think this way.

Have you ever seen a squirrel with antlers? Well they have been living on Thalos for centuries. and just recently the first are spotted on Earth...

Somewhere in the alps (where the cave is located on the "earth-side"), these creatures have been spotted traced back to the cave by hikers and explorers. Most of these people wandered into the cave voluntarily, others may have been kidnapped by Sagoo-guards.

The more these two worlds mix their ingredients, the more confusion and chaos it will bring.
