After beholding the destruction of the Well-Built City, physiognomist Cley is now a simple healer seeking peace and atonement in the happy village of survivors. When the town falls into a deadly sleeping sickness, Cley must make a dangerous trip to the ruins of City - now beset by mechanical birds and werewolves - to seek out an antidote.

The evil Master Below is still alive, but an accidental exposure to the sickness that he created has put him into a coma. With the help of Below's adopted demon son, found in the wreckage of the laboratory, Cley ventures into the mind and intricate memories of Below to search for a cure.

Cley will encounter wonders and dangers undreamed of in the second installment of this classic trilogy.
