Terra Mystica Fire and Ice

Fire and ice descend upon Terra Mystica! The traditional factions must brace themselves for their new competitors: Yetis, the masters of power; Ice Maidens, who adore their Temples; Acolytes, whose entire life is focused on the cults; and Dragonlords, whose use their power to create volcanoes. And, as if this wasn't enough, there are two more factions (Shapeshifters and Riverwalkers) who ignore the most basic of rules: one faction, one terrain type (Inconceivable to the Halflings!)
