Adrian Tchaikovsky returns to the world of Elder Race.

Nyrgoth, taken by the people of Sophos IV for a wizard commanding ancient iron giants, is in fact the last guardian of a forgotten technological civilisation, and he is drawn out of hiding when a vengeful outlaw unearths buried machines alongside a witch who can command them and who speaks his own lost language.
