Books like last guardian

The Last Guardian is a 1989 British post-apocalyptic heroic fantasy novel written by bestselling British author David Gemmell.

The Last Guardian is a sequel to Wolf in Shadow, taking place about two years after. The Hellborn are no longer a threat, and all but two of the Guardians are dead. Additionally the largest source of Sipstrassi has been destroyed making the stones much harder to come by. Additional details of the world are also revealed as we learn by the end of the first novel that the city of Atlantis did exist, and sank in the first "fall", the story of which time has been passed on as the story of Noah's ark.

As in Wolf in Shadow, The Last Guardian's magic system is based on Sipstrassi or stones of power, which are golden meteors which allow one to heal oneself, create food, and which are supposedly limited only by one's imagination, although each stone only has a certain amount of power, and as they are used black veins will appear upon the stone and grow, until eventually the Sipstrassi is coal black, and powerless. However by feeding Sipstrassi blood one can refill them, although Sipstrassi refilled in this manner become blood red, incapable of healing or producing feed, good only for combat. Additionally blood Sipstrassi inspire darker feelings such as lust, greed, and rage in their wielders.
