According to legend, three galactic terraformers shaped your planet into a paradise. When their work was done, they left the source of their power behind: three golden hexagons, hidden in dungeons full of traps and monsters. If one person were to bring all three together, they could reinvent the world however they saw fit. Can you collect the hexagons before your rival? Dennis E. Shasha shows how.
