In our history, in 1242, abruptly on the death of their overlord, Ögedei Khan, the Mongol forces ravaging Europe withdrew.
"Against the Devil's Men" envisages Ögedei living just ten years longer and the Mongol advance continuing unabated.
By 1267, the Papacy has retreated to eastern Spain and a front line runs from Celestine's Wall in France up to the River Rhine in the German states. Against this background, an exceptional friar, Brother Cataldo, the half-Mongol Sister Aurea and a hardy band of Cuman warriors, are sent to spread disease among the Mongols in the desperate hope of stemming their invasion.
