The Nemesis Bestiary
A science-fiction bestiary for the Galaxy Command d20 Future setting, introducing original alien creatures for use in spacefaring adventures. Each entry provides game statistics and special abilities, while reports from survivors reveal fragmentary and sometimes contradictory accounts of the creature’s history, behavior, and motives. Game masters can use these clues to develop encounters and expand the creatures’ roles in their own campaigns.
