Verpine

"Verpine choral arrangements. They don't sing, they just rub their legs together!"

- Sabine Wren, in her personal journal

The Verpine were a hive-based sentient species that controlled Verpine Roche Hive, a droid manufacturer that produced the 8D-series smelter droid. Instead of singing, they rubbed their legs together to produce Verpine choral arrangments. The Verpine were the namesake of the cruciform Verpine ratchet.

Behind the scenes
The Verpine first appeared in Star Wars 7: New Planets, New Perils!, the seventh issue of the original Legends series of Star Wars comics published by Marvel Comics, which first went on sale on October 11, 1977. The species became canon when it was mentioned in Star Wars Rebels: Sabine My Rebel Sketchbook, a young readers book that was written by Daniel Wallace as the in-universe journal of Sabine Wren, which was first released on February 3, 2015.
