Blast
Faunas were the big creatures. Each fauna hoarded group of wild creatures. There were only three big faunas in the Oak park. They were at the three different places. The last fauna had been protecting the card.
The faunas were the first creatures to find the gem card. It was middle in the night back then. The gem card emitted few lights and they took it thinking the entity that was protecting the Oak Park.
From then on the Faunas decided to protect this gem card in order to keep the Oak park stable and alive.
Now that the teams entered in the Oak park, it was bound to create chaos. Third team heard the blast. Jake got alarmed. It was at the left side and the distance did not seem much.
The liquid fog from the area vanished because the Oak trees got blasted. The opponent team happened to see third team. They got excited thinking that their plan worked.
