For centuries, Earth was inhabited by hordes of vampires, werewolves, demons, and zombies. But generations ago, Sela Mathers, the Guardian of the Nexus, was able to banish these creatures to a long forgotten Realm called The Shadowlands. For over a century, these hideous monsters have remained trapped there... until now. A nameless, god-like being has released legions of monsters from The Shadowlands back on Earth, and now it's up to four expert monster hunters to do what they do best: find and destroy them.
