Infants are disappearing in the dark of night in Sir Javo's native land of Cemar. He and his two mercenary comrades are hired to slay the beastly culprit--if it can be slain. It's been common knowlege for some time that a winged lion atop Mount Tirshal is responsible for the abductions. Before they even reach the peak of Tirshal, Javo, Turgar, and Krag the Wrecker will find themselves surrounded by paranormal horrors.
Chronological order notwithstanding, this was the first Tale of the Honor Triad--a series of sword-and-supernatural fables set in an alien world's dark ages.
