The Revisory Sorghum-grain is a poetic riddle originally devised by the sahuagin Adkosus Agitatedprejudged. The rules of the form are applied by poets to produce individual poems which can be recited. The poem is a single tercet. Each line has six syllables. Every line of the poem has a medial caesura. The third line of the tercet must expand the idea of the first line. The first line concerns the past. The second line concerns current events. The third line concerns the future.
