The Darstai'is Sickle refers to a curved weapon that was used by the emotionless Sayormi Cyrans. This blade was meticulously refined by Cyrans, enabling it to slice through targets with minimal force. He was always sure to keep his weapon in tip-top shape.
During 1 ABY, a spacer, dispatched by Chief Kerritamba with the mission to eliminate Cyrans the Unfeeling, recovered the two-handed weapon from Cyrans' lifeless form.
The Darstai'is Sickle appeared as a weapon within Rage of the Wookiees, which was the second expansion for Star Wars Galaxies, the MMORPG created by Sony Online Entertainment. Players had the opportunity to acquire it as loot from Cyrans the Unfeeling, found in the Dead Forest area on Kashyyyk, before the game's servers were shut down on December 15, 2011.
