Publisher blurb (edited to clarify ruleset required): From the author of Gamesmen of Kasar, this solo adventure is set on the planet Bollux IV in the same fun but lethal spirit as that classic adventure. This is a solitaire adventure for a single 3rd-, 4th-, or 5th-level character created from the rules of Tom Loney’s New Khazan or Ken St. Andre’s Tunnels & Trolls. You will need one or both sets of rules to understand and play the game. Warriors, Rogues, or Wizards may play, but magic users may find their spell-casting ability severely limited in some parts of the Game complex.
