The sector designated as the Glacial Fissure is almost entirely White Maw territory. The deep ice canyons and extensive underground cave networks provide shelter and staging areas for the vicious pirate forces. When the White Maw's leaders saw the Republic and Imperial militaries arriving on Hoth, they immediately established well-defended camps and supply routes throughout the area.
Traveling through the Glacial Fissure is suicide for all but the most well-armed and highly trained operatives. The White Maw pirates do not fight conventionally, preferring to set ambushes and traps for their victims. Both the Republic and Imperial militaries have sustained heavy losses here, demonstrating the extraordinary threat the pirates represent.
