The Chronicles of the Dark Realm

Behind the veil of our world lies a realm no one speaks of.
Its creatures loom in dark corners, its narrow paths are not traveled by mere mortals, and one cannot tell apart the heroes and villains hiding in its shadows.
This world within our world has shaped the course of history since the dawn of time, but you'd find no trace of it if you searched, and anyone with a brain would advise you not to.
It takes a very special person to handle the truth.
Can you?
Two friends as close as brothers stumble upon this world by accident during a camping trip, and their lives are changed for good.
Transformed by this encounter in horrifying ways, they find themselves lost in this unfamiliar realm.
As they try to decipher the meaning of it and harness their newfound abilities, age-old enemies hunt them down, making survival a quest of its own.
Can they make it out of the Dark Realm alive?
Do werewolves bite harder than vampires?
And when it comes right down to it, who is evil and who is good?
If you think you know these answers, you must know nothing of this world...
