Treb is a plant cultivated as a crop on Roshar. Unlike most Rosharan crops - such as lavis, tallew, and clema - treb is relatively low maintenance and can survive flooding. Treb is a vine that grows clusters of hard pods which contain grain. The farmers above Yeddaw plant it in slits in the stone. As it grows, the vines help anchor the plant and the pods grow wedged in so that they don't get blown away by the highstorms.
It has yet to be reviewed.
