The planet of Crucival was where the soldier Hazram Namir commanded a group of soldiers. Among them were Pira Ten, a friend Namir made during his time with the Opaline Creed, along with Tar and Mishru, former adversaries who joined Namir after their leaders vanished. The Galactic Empire enlisted this group in 0 BBY to assist in protecting their tower from the Rebel Alliance's 61st Mobile Infantry. Sadly, almost all of them died during the initial assault of the battle, leaving Namir as the sole survivor when the conflict concluded.
The novel Battlefront: Twilight Company, penned by Alexander Freed and released in 2015, marked the initial appearance of Hazram Namir's group.
