Raiders of Scythia: Omens

From BoardGameGeek:

THE STORY To the skies they look, those mystic Aneraeans. Horse and rider wait for blessing or forewarning. As the storm clouds pass, and the heavens glow with golden rain, the beating sound of steeds upon the steppes are heard once more. EXPANSION CHANGES The Omens expansion adds new Heroes, Crew, Animals, and an updated Game Board. It also introduces Omens, which add new rules for raiding and completing quests in specific areas. These new Omens tie in the new Shields, Purple Dice, Kurgans, and more twists to each game. -description from the publisher
