Jehen'u is a male Jaffa from the planet Dashani . He was previously Fourth Prime of Ra . He was stationed at Dashani with several of Ras Jaffa . In 1999 , when SG-1 were involved in the trial of men urged Jehen'u Daniel Jackson to see if the Jaffa on Dashani would send a spaceship to pick up him and his Jaffa so they could leave the planet they were trapped in.
