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, namely Shapeshifters and Riverwalkers, who ignore the most basic of rules: one faction - one terrain type. (Inconceivable to the Halflings!)
