The Lavender Earth is a poetic form intended to express pleasure with the deity Sethe the Windy originally devised by the elf Ilime Mistycovered. The rules of the form are applied by poets to produce individual poems which can be recited. The poem is four to five tercets. A form of parallelism is common throughout the poem, in that certain lines reverse grammatical structures. Each line has nine syllables. The third line of each tercet reverses the word order of the first line.
