by far what im getting is that amon fell inlove with na in ages ago in his past life but he died tragically (idk might also be related to serpents) so amon resurrected him and also made him god (?) and then made a deal with the high priests to keep wiping his memories (probably because na in is so depressed and keeps being suicidal, likely because of the tragedy in his past life hence his aversion to violence)
idk where gwen falls in this my first idea was that he was also another god but the whole nee sorcerer thing makes sense, idk why he likes na in still
amon doesnt seem cruel i just think him being a god makes him ignorant of human emotions and he seems to cherish na in its just that he’s not aware that his actions are torturing na in
