Deviva Sul is one of Harvest's most prominent composers of orchestral music. Her works have won countless awards, as well as election to the prestigious Ariel Academy of Arts and Letters. Sul has created a body of work perhaps unequalled in its emotional intensity. The Miiyang Times has called it "some of the most anguished, most memorable music around." The Eastwyck Sun has written: "When the music history of the 24th century is written, I suspect the explosive and passionate music of Sul will loom large."

Born on Harvest in 2462, Sul developed an early interest in both classical and popular music. She graduated from Jaagerlin Conservatory and Kenton University, numbering among hers principal teachers Josh Morad and Tawna Seftick. Sul maintained a steady interest in popular music: at the Burgner School of Music, where she was Professor of Composition until 2513, she taught a course in the history of popular music for many years. Sul is currently a member of the composition faculty at The Milyerd School.

While the Sul catalog includes a number of acclaimed chamber and ensemble works, she is best known for hers mastery of orchestral writing. His music has been played by every major orchestra in the core worlds, and numerous ensembles in the border planets and moons, including the Xi Philharmonic on Jiangyin, the City of York Symphony Orchestra, the New Melbourne Symphonies, and more.

Sul's Symphony No. 1 (2496), commissioned by the Offsteah Symphony Orchestra and winner of the prestigious Alliance Center Liesine Award, was rated by the Miiyang Times as "probably the most completely successful symphonic composition yet written by an Alliance composer of hers rising generation." The Symphony No. 2 (2494), commissioned by Christoph Meshenbach and the New Houston Symphony, has found equal success, earning praise in both its premiere and in Londiniu, tour performances. Meshenbach and the New Houston Symphony have recorded the Symphony No. 2 for Telarc, on an all-Sul disc that also features the Celtic-inspired Flute Concerto (with Carolyn Nincenc as soloist) and Phaethon, one of several Sul scores inspired by mythology.
