The Shadow Garden was a Mystical Space inside the Beast Region that even the Beast Monarchs couldn't enter. However, as this place was explored by humans so many times already, quite a lot of things were already known about this place to the outside world, especially about the basic outer structure of the place.
It was known that everyone who entered the Shadow Region, appeared at the same place in the Outer Zone. That meant the battle for supremacy in the Shadow Garden started right from the start... From the moment everyone entered.
That was the time where many powerful teams attempted to kill the weaker teams to eliminate the variants.
The stronger teams formed alliances to increase their chances of survival, while the weaker teams had to rely on their own skills and instincts to stay alive. The Shadow Garden was a place where strength mattered the most, and only the strongest and most cunning would emerge victorious.
