Karachi Cards

The Karachi Cards, distinctive octagonal playing cards featuring star and comet suits, emerge in the Red Rising Saga as a favored tool for probability-based gambling among Obsidians and societal elites. First prominently featured in Dark Age, they add a layer of cultural texture to high-stakes Rim environments, symbolizing the blend of savage Obsidian traditions and refined Gold pastimes. Though their role remains niche across the series, the cards underscore the saga's intricate world-building, evolving from mere gambling props to evocative markers of interstellar leisure amid galactic war.
