Esse é o Inverno do Mundo por Mike Scott Rohan (sem relação). A trilogia original foi posteriormente ampliada com mais três livros.
The Winter of the World stories are set in a strange and hostile time, one of the eras when the Great Ice spread out yet again from the polar caps, seeking to engulf the world in its chill grip and scour it clean of contaminating life - and most of all the first, and long forgotten, civilizations of men. But, as the Winter Chronicles record, men were not wholly without friends; and they found in themselves strange and magical abilities to help them survive and keep the lights burning against the encroaching dark. Greatest among these was the working of metal to arcane effect, the power of smithcraft; and the men in whom that power burned fiercest of all became the source of many legends, the Mastersmiths of the Northlands.
