Roti
this grain was a staple in the diet of the Seratians. It was also consumed by tymps who have migrated into urban areas of the planet Serat, after the Seratians decimated the population of symers. The symers preyed on the tymps, keeping their population to a minimum. However, the Seratians killed off the symers in order to obtain their organs and appendages, which supposedly had mystical powers. This allowed the tymp population to explode, and virtually destroyed the roti crops on the planet.
