Cryptid Fight Club

There are creatures lurking in our world. Obscure creatures long relegated to myth and legend. They have been sighted by a lucky-or unlucky-few, some have even been photographed, but their existence remains unproven and unrecognized by the scientific community.
These creatures, long thought gone, have somehow survived; creatures from our nightmares haunting the dark places. They swim in our lakes and bays, they soar the night skies, they hunt in the woods. Some are from our past, and some from other worlds, and others have always been with us-watching us, fearing us, hunting us.
These are the cryptids, and Systema Paradoxa tells their tales.

PI and retired MMA fighter Rufus Griffin pounds the streets of Vegas on the tail of an unfaithful spouse, but what he finds is a tale of another sort. One of intrigue and illicit fight clubs and cage bouts too incredulous to believe, even when he sees the fighters with his own eyes.
He keeps his head down and stays on task until he discovers those in the ring aren't there by choice. A victim of abuse himself, there is no way he can leave them to their fate, even when his official business concludes.
Rufus Griffin dives back into the underbelly of the Strip and comes out fighting.
