Someone has interfered with history on a Q5. They introduced a genetically engineered grain with the flavor of wheat, the resistance and durability of Rye, the nitrogen-fixing bacteria of a legume, and enhanced nutrition. The present year in this world is 1290AD and the population of Europe is fifty percent larger. Finding when, where, and why, this genetically engineered crop (called Mazlin) came about is vital.
The higher population combined with the oncoming
Little Ice Age seems like a plot. But is it to collapse Europe with more brutal famines, to help Europe make it through the famines and plagues of the 14th century, to alter the future center of power, what is the point?
You can send your PCs all over medieval Europe chasing the non-domestic geese. Or, push the clock along and set the adventure in the chaos of the insane rains and other weird phenomena of the end of the
Medieval Warm Period.
