ly everyone hates liches - those Lords of Sorrow - more so even than vampires, dragons and demons. They taint everything they see and are sentient, free-willed open wounds in the fabric of the omniverse. They are possibly the grandest form of blasphemy known to exist.
A Lord of Sorrow that rarely, if ever, leaves its crypt is not as frightening as one that frequently goes hunting for souls to eat. A lich that rarely, if ever, looks up from its magical work is not as useful to a game master as one that wants to collect the heads of the player characters as horrible conversation pieces.
So, here liches are given reasons to get up, go out and be horrible.
The purpose of this book is to expose a Lord of Sorrow on many levels: its magic, its mind, its goals, so forth and so on. In so doing, liches should become a more flexible tool in the hands of the game master, and the player character may become better prepared to deal with them - and players may even run a lich.
