Lots of good questions. A "good person" who isnt religious (ie: isnt claimed by a good god) goes to Arawn's realm. "Bad people" are supposed to go to hell, though their amount of wickedness determines where they are dumped. The swamp gets the vast majority of these. Thats how it is supposed to work. But the agents of hell are ever eager to collect as many souls as possible, even those that rightfully belong in other vaults. They fight for these souls when the people are alive, and they continue to fight for them when the people die. The swamps of Mulcarns realm hold many spirits that may not have been greatly virtuous, but dont deserve the eternity of hell either. Spoiler from the conclusion of Lord of the Balors : With the light came angels, not the barbaric ones that traveled with Basium, but gentle compassionate creatures that tended to the wounded men and spirits alike. The darkest spirits had been dragged into hell when the Throne of Hell was destroyed, but thousands still remained, those stolen unfairly by the demons or trapped between the ideals of heaven and the failure of hell. I walked among them, blessed souls seeking forgiveness, shared the pain with those who had carried it alone for so long. Other members of my army were the same, weary but unwilling to stop tending to these souls. It was as if we rescued a kingdom under a cruel despot, but no one had suffered as horribly as these souls had. For many it was the first kindness they had experienced in centuries.
