Following the life of William Santiago, the Prince of Wolves, we see the cusp of glorified reign in the eyes of the Prince and the inheritance he is expected to receive. In the realm of the supernatural, in a struggle for dominance; the world of werewolves and vampires alike collide in epic reveille. William Santiago is a Prince bred for the singular purpose of bringing an end to that timeless war. In The Monster Within, we see the werewolf royalty, called the Elder, from the eyes of the prince; the dark shroud he weaves finally coming to light as we get to unravel what is myth and what is truth. Spiraling through time, we witness the hidden scrolls of life around the ageless family feud for dominance as William strives to leave an indelible mark in the world. However, sometimes the struggle is closer to home, and as we watch William's story, and take part of the various rising and falling of those around him, we cannot help but to wonder where next does the enemy at the gates come from? Perhaps, the monster within is all too close.
