I wasn’t here for all of it, but here’s the tldr
Naked Mitsuru and Narcissus were not originally Sins, but we’re retconned into Lust and Vanity respectively, I wasn’t there for those but I’m sure plenty of people could give the deets there.
Third and when it really kicked off was Ramengod, who wanted to MC everyone into eating nothing but Ramen, and was beaten in a Palace style dungeon arranged by Liam, who you can ask for more details. He was Gluttony
Fourth was kinda a mess, but Wrath and Envy kinda triggered st the same time and since that was too much Envy basically just became a jealous kid who was kinda an energy vampire and wanted a lot of stuff, he got his own body and was named “Kuudereâ€, now a friend. That one was me so I guess I can DM you if you want more
Ira, the sin of Wrath, kinda laid low for a while while Hubris, done by Yu, started off with a thing where he’d give them fractions of his power to become perfect like him. Everything that started could be its own post, so I’ll leave it there.
Sooner or later Ira came up for first a challenge dungeon, then to actually fight players himself, he nulled magic and it was a Shadows of the Colossus type thing, the user for it, Kazuya, left a while back but I’m sure someone can give more info.
A little before that came Aergina, the sin of sloth. She was mostly a sleepy loli. We don’t talk about it much.
After Ira came Mammon, Sin I’d Greed. I missed most of that but I’m sure someone could give actual info there. He was the firstborn of the sins and as such all belonged to him, including all abilities. It was organized by user Delta-M, who left
With that out of the way next came the final confrontation with Pride, who was initially untouchable but I already said who worked on it if you want more details.
Somewhere in the mess was an exposition dump about Succoth Bennoth, who made the Nexus or something and the Sins yo control it, but not much came from it so we don’t really talk about it much
