With the West behind them, the travelers have the task of continuing on through the Great Beyond towards Chiloe and the East. Between them is something far worse than Lord Pazlin however. With the Phanthow as the driving force for the majority of the beings inside of the massive mountain range, they find out quickly enough that they have come from one evil force to a potentially greater one. Driven still by History, the group must proceed on, defeat the disturbed and mutated creatures controlled by the Phanthow, and exit the Great Beyond into Chiloe to hopefully get on with their original quest. Extreme: Book Four of the Phenderian Series takes the conventional wisdom that the band has lived by, and creates an entirely new set of rules.
