I never knew that so many ghosts lived outside of Sepulcrum. When I asked Daemon while we were walking to Maisha’s hut, he said that Sepulcrum is where those who have picked a definitive side in the war live. Those who have picked my side. Gahenna is where those who have picked Kendra’s side live. The ghosts in what Daemon referred to as “hostile” dimensions, such as Hölle, just follow their leaders, but could go either way if given the chance.
But the ghosts in Jahanamu are completely different. The ghosts in Jahanamu are completely neutral. This is where those who died during wars or times of conflict live. This is where those who just want peace in the afterlife live. Jahanamu is a safe haven for the dead who do not wish to fight or who do not care about the civil war.
Jahanamu is a model for what the entire supernatural side could be like if Kendra were dead.
