The Trollbloods have suffered for decades at the hands of outsiders, and the infernal invasion was yet another human atrocity that punished the kriels. The infernals had not come to Caen for their souls, but the cosmic horrors still slaughtered the children of Dhunia whenever their forces crossed paths.
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.
