OK so I'm now leaning towards the story being post LOTM considering it is said that the church of eternal blazing sun hunts down warlocks and witches, so its probably common information. And warlocks are just another name for Beyonders which became widely know after the world war so this is prolly post LOTM

Okay maybe the story is 1 year before the end of LOTM or someway before the end considering they mention the church of the god of combat without the church of the fool

Story might me post LOTM since they refer to it as Roselle's diary instead of Roselle's notebooks

I'm not sure if the author actually implemented it but after reading the authors interviews on the reddit, I read a part where he said the story takes place 1 year before the end of LOTM so I'm not sure if this is pre or post LOTM anymore cuz Frank Lee is well known
