Mysteries of the Occult
This supplement expands a modern occult setting of rain-soaked streets, hidden Scope domains, and dangerous Etherspace. It introduces demon hunters, ritual occultists, secret societies, strange creatures, and ancient civilisations that survived before the Earth-Wrack. Players gain new occult talents and feats, along with seven advanced classes and four prestige classes. The material also explores demons, System agents, the Great Old Ones, and the mysterious forces behind them.
