From what I understand, there are 3 original gods that govern this world of Lona, but a 4 appeared that usurped the authority of the others and weakened them, generating chaos. The undead and humans are under the authority of Justice, who is probably the necromancer god, but His authority cannot affect areas where they are under the authority of a stronger god.
The Saint is not a trustworthy divine being and not all humans follow him faithfully. Justice is probably the possessor of the Authorities over Humans and the Undead, as death comes to everyone, especially humans, and he is probably death disguised as Justice for all the corruptors of this cursed land, law to the incredible adventure review text with the fortune-teller and very bad , but very interpretative.
Remember Nicholas. Quest with the murder of Pighead. The mother of fertility is obviously the Fortune Teller. But Nicholas, her Child, decided to squeeze out some of the divine powers from her mother. In addition, according to the Sea Witch, it is known that there are both good and bad gods. Seems like good ones: Fortune Teller, Sea Witch, Justice. Doubtful: Holy, but he gives the priestess branch. Bad: Cthulhu, Black Mist (Nicholas)
