Even in the world of Grimm and magic, there are much more outlandish and anomalous things that hide. A long time ago, long before Salem, there was a forest called the Unknown. The Unknown was the home of many mysterious and exotic wonders, but also dangerous. The vast forest kept one such creature that all feared, even it's name stop the beating heart in fear, The Beast. The Beast was once known throughout all the world. He cannot be mollified like some farmer's pet. He stalks like the night. He sings like the Fall winds. He is the death of hope. He steals the children. But, time has eroded the legend into myth, and the myth into nothingness. But, that didn't stop him, no it didn't matter. Because The Beast always needed people for his lantern. And now, that the world has changed so much, what place does The Beast have in the war?
