I like to of chaos as what Clive Barker made Hellraiser. In which it waits unopened to the human eye but beyond the Vail of time is a realm that is ever moving ever changing. Filled with screams of pain and pleasure, the blood spilling. Filled with such horrible beautiful things, that to look upon them would drive beings that can't comprehend totally insane. For we Chaos reborn sons & daughters, this is home to us. We are the gifted ones, we are the chosen ones. The loyalists and normal beings can't help but look upon the realm of chaos with disgust and fear because they fear what they don't understand. Now not all can be embraced by chaos because if there are no more sheep the wolves will go hungry. So we must heard the sheep and feed when we can do we can breed new wolves to follow in our footsteps so they can bring truthfulness so the sheep can stay on their path and the cycle of life & death can always move forward.
