As the infernals came for human souls, refugees fled to all corners of Caen (and beyond) to escape. Many of these refugees found themselves in troll lands. There, some were welcomed allies while others were not. No matter their allegiance to the trollkin, many of these survivors brought with them their stores of supplies, including weapons and ammo, which Brigadier General Gunnbjorn happily accepted in return for sanctuary among the trollkin.

It was not long before the brigadier general organized the first units of barrage teams, trollkin trained to use cutting-edge rocket launchers acquired from the human kingdoms. With plenty of ammunition available, the barrage teams are allowed to fire into enemy lines repeatedly, scorching the battlefield with their devastating blasts.
