Runar Gameplay (We made up a scenario!)

About Runar, from BoardGameGeek:

“They saw The Dreki of Odin and the other Gods in the grey sky. They came to save the beloved Mannheimr from the bloody invasion of the Jotunn. The Gods came down from the sacred ship, gliding on their shields, surrounded by flaming embers. I spent my whole life looking for the place where they landed and where the battle took place, I'm finally sure I found it!” The sound of the horns cuts off the old Alfarinn. The Drekar from each clan depart the Roskilde harbor, bringing on board the most valiant and skillful heroes. The hunt for the mysterious Runic Gems, fragments of divine power, has just begun! Runar is a competitive board game with high interaction and comic-style miniatures. Each player forms and guides a Warband of three Viking Heroes through frozen and harsh lands, teeming with savage and lethal creatures. Earn victory points by defeating powerful Enemies, retrieving valuable Runic Gems, completing various objectives, and defeating opposing Heroes. Destiny Cards mark the unique moments of the game and trigger the final round. The Warband of Heroes with the most victory points wins the game and grants access to Ragnarok! Play epic single matches, with Heroes at full power, or play a 5 episodes campaign, evolving your Heroes during the journey. -description from the publisher
