Maize Cultivation (innovation)
While most of the shattered_coast has built civilization through the cultivation of wheat, the people of the The Kasiryat and Kashirya have a storied history cultivating maize, and know well how to prepare it correctly.
"The Chan Skorpokaipis wiped our histories away in tides of tragedy. There is no end to the roll of what we have forgotten. From each ruination has sprung the same ears planted in the same way. Maize, it seems, we can never forget."
~ Vadhan, 'Ruminations'
