This is the story of Lars of the Puma clan, of the people of the Smoking Mountains. Lars's father was of the famed Star Men- explorers of the blasted wilderness beyond the mountain stronghold of the Star Hall. The brotherhood of Star Men sought to carry on the tradition of their research scientist ancestors- to seek out new knowledge for the betterment of the tribe- and of the world. This was to be Lars's destiny also, except that his father failed to return from his last mission and there was no one to speak for him at the last choosing of apprentices. So, rather than accept the insult of a lesser life, Lars took up his sword, bow, and his father's pouch, and along with his great mutant hunting cat, Lura, went out to find the great lost city of the Old Ones that his father's last journal entry spoke of.
