From the announcement:
Following the success of their first card game, Fairy Rade™, as a Print On Demand (POD) title offered via DriveThruCards.com, Green Fairy Studios LLC has released their second card game as a POD title as well. Lygari!™ is a bluffing card game for 3-6 players, where each player takes the role of one of the Einherjar, the spirits of Viking warriors, in Valhalla, boasting about their quests in their former lives. Players make claims to defeating various types of creatures from Norse myth, but may lie about which cards they have played. Other players must judge when to call each other a “Lygari,” a liar.
Lygari!™ is the second in a series of games to be published by Green Fairy Studios that explores various ancient myths, including Norse, Celtic, Greek, and others.
