[To Coin a World] The Dwarven Agricultural Revolution

-200 years: dwarves subsist primarily on fungal products, poor mountain-side farming, and trade with human farmers

-150 years: clever dwarven runesmith inscribes rune for sun on seeds of barley plant, leading to plants that can grow out of the sun

-100 years: sun-free barley farming becomes reasonably common in the dwarven mountain holds. surface farming communities are abandoned (ruins!), holds become more crowded as the dwarven population grows

-50 years: growing population pressures spark massive social discontent among suddenly large population of young dwarves, leading to internecine clan feuds and gross migration out of dwarven communities and into human cities

-50 years to present: human and dwarven communities become more tightly integrated thanks to migration. dwarven holds develop new mines and mining techniques that vastly increase the supply of metals across Spindewick. pri
