Luna and Knight enter Greed's penthouse suite. The lights and the fireplace are off. Nobody is present in the room.

Out of the 3 windows, they see:

Gluttony is experiencing a severe forest fire! Lust is fine. Envy is stuck in daylight but appears the same as when Harmonia and Spider were there. Pretty standard and beautiful forest! The lights of the radio towers blink in the distance.

“You know, this is most likely going to take more than one trip,” Knight says.

"Probably. Not to mention, I have no idea what the hell the remnants issue even means." Luna responds.

“It most likely has to do with Mammon being around,” Knight says. “Since he is, ya know, Supposed To Be Dead!”

"Right. Anyway, let's find some leads." Luna looks around the penthouse, looking for any evidence of Mammon's revival.

“Alright” Knight takes out a flashlight and starts looking around.

It's just the penthouse. Lots of bookshelves, nothing about Mammon.

Although, Knight comes across an EXTREMELY EXTREMELY EXTREMELY dead Orobranche flower in a glass container.

Knight stops moving and stares at it.

It's dead!

He stops looking at it and looks for a way to leave.

There's a door.

He opens the door and Luna glances over. "Oh boy. Guess we're heading out."

They both head through the door which leads out into a random place in the Library.

"Hoo boy. Time to get lost in the Library of Greed." Luna looks around.

“Time for some disorganization I guess,” Knight says.

The door shuts behind them and they can see they’re in the history section.

"Ew, where's the manga?" Luna asks.

“I wonder what history they have here…” Knight starts walking forwards.

Luna follows, staying right next to Knight. "We need to stick together ok?"

“Alright.”

Eventually, they come across a small 4' crow sitting on the ground. They're wearing a WWII US Army Helmet and eating poker chips by the handful.

Knight walks over to the crow and taps it on the shoulder.

"Hello?" Luna asks.

“Where did you get those chips?” Knight asks.

"Uhhh why are you eating poker chips?" Luna asks.

They squawk!

Knight tries to take one of the poker chips.

They let him!

Knight takes a good look at it before putting it into his pocket.

"BITCH!" Yells the crow with the same big dopey smile.

"Hey uh where did you get that chip?" Luna asks with a smile

“Takes one to know one~” Knight says.

"Cooooooole Genesone!" They say it in a very chipper and exaggerated way.

“Uh-huh.” Knight says.

"Oh. Is there a place with more of these things? Like it's a poker chip, so is there a casino?" Luna asks.

The crow hops up and squawks at them, giving an excited nod!

"Let's follow them, Knight!" Luna says

“Alrighty then!”

The crow starts to walk off in the direction Knight and Luna had come from, the section now various pulp novels from the 50s and 60s

Knight follows the crow.

Luna’s just following alongside Knight, making sure not to get separated.

The crow is taking a lot of quick and sudden turns.

The two follow and eventually the floor gives way to an endless black void and the crow hops right in! No hesitation!

“Well that explains nothing,” Knight says.

"Shall we jump in with the same lack of hesitation?" Luna asks.

The two jump in and find themselves falling in an infinite black void. It is bottomless. The crow is below them and is looking up at them with the same stupid smile as when they met.

"Well, this is fun." Luna says.

“This is great.” Knight says sarcastically.

Luna's just fuckin jamming out to music though. Infinite black voids are a lot more fun with Dragonforce.

They suddenly stop falling and with an abrupt thud and an explosion of poker chips, they land painlessly on top of a poker table that was currently being used by a group of crows who stare in astonishment.

Knight and Luna find themselves in an incredibly run-down one-room casino! The lighting is bright and all but the tiles on the floor are cracked and the lettering on one of the walls is EXTRA faded but they can make out an M A and N strangely spaced apart.

There are a lot of crows just gambling and drinking alcohol!

Knight gets off of the poker table and looks around. “This is definitely what someone would say Greed looks like.”

Luna is still headbanging. "Huh, yeah, this is definitely Casino of Greed vibey." She gets off the poker table and walks around. "MA...N? Mammon?"

“Most likely,” Knight responds.

"Okay, so now we need to figure out what the heck a remnant problem is," Luna says.

“Doesn’t remnant mean something left behind or a little bit of something that should be gone?” Knight asks.

"...oh...Okay, I think see why Enoch was worried about this one then. It might be this casino then. It's a remnant of Mammon's." Luna says.

The crows resume playing poker while the crow they followed sits on the table and eats the poker chips.

The main 3 games being played are blackjack, poker, and slots. There is one extremely exhausted-looking male crow in a playboy bunny uniform running around with a bottle of whiskey refilling every empty cup in sight.

Two important looking things:

A book stapled to the wall with a single word circled next to an opening that leads to an upward staircase.

A chip exchange area! There's a crow with a tophat sitting at a desk in the caged-off area, There are a large amount of safes and also an old-looking computer.

Luna migrates toward that weird lookin' book.

Knight follows Luna.

It's a book stapled to the wall. It has the word "library" circled on one of the pages. It appears to be a trashy gay romance novel.

"Library. Also, that's some..." Luna reads it. She sorta regrets it. "Yeah, that's definitely very."

“That’s good to know,” Knight says.

"Shall we investigate up the stairs?" Luna goes up those stairs.

Knight follows.

It leads into the library. If they walk too far, the entrance to the Casino might disappear.

"Huh. Okay, let's turn back before we lose access to this place." Luna says.

Knight heads back down to the Casino. “Yeah.”

Luna follows. "That reminds me, I was going to come here with Legion. Glad it all worked out haha.”

“Yeah” Knight heads for the chip exchange area. Luna follows.

The tophat crow is asleep at the desk. He seems to have been playing solitaire.

Knight gets out an air horn and honks it.

"Ayo wake up!" Luna yells.

They fall back out of their desk chair. "WAUGH!!" Thud.

“Sorry to wake you but I have a question to ask,” Knight says.

"Uhhhh sorry about that!" Luna says.

They get up and put their hat back on. "Are you going to ask for a ludicrous and ungodly amount of money too????"

“No? I just wanted to ask if a person named Mammon is around.” Knight asks.

"Hwh..??" The crow seems shocked and confused. "Why are you bringing him up n o w??? He's been dead for ages!!!"

"Right, that's what Legion told us as well," Luna says.

“Just wondering,” Knight says.

"We were sent down here to solve an issue y'all were having with remnants. And we were wondering if anything left of Mammon was causing you guys any problems." Luna says.

"..uhh..." The crow pauses. “There's. like... a private and illegal no entrance zone? but it requires a special.. thing. to open. And I don't have it, so..."

"...hm. And what would this thing be?" Luna asks.

"..uhh...It's, like...So you know when you have like... a door without a knob and it's like.. recessed into the wall?" The crow asks.

"...oh. You mean like a card key?" Luna asks. "Like the door would just slide open."

"Sssort of..? But it has like a strange keyhole that a key wouldn't fit in. More like it's asking for an object?"

"Hm. Do you what kind of an object this special door needs?" Luna asks.

"It's like very.. weird shaped. Part of me thinks like a sword or a knife but that just sounds weird and stupid who the hell would do that???"

“Or maybe part of an Antler?” Knight asks.

"Maybe??? I feel like an antler probably wouldn't... fit. But maybe?" The crow responds.

“I’m not talking about an entire antler, just a small piece,” Knight says.

"Maybe."

“Hmmm, okay.” Knight says.

"Well, we have a lead toward our issues. A door that requires a special object. Wanna try the antler piece on it, Knight?" Luna asks.

“I don’t have one, I only brought it up since it made sense for a lock that leads to an area that holds the remnants of a dead prince,” Knight says.

"Ah. Right. Hmm. How about that computer? Does it have anything about Mammon on it?" Luna asks.

"N-no...? I mean I have access to his bank account?" The crow says.

Luna tilts her head. "He still has a bank account after all these years?"

"I mean yeah it's where I pull all the casino funds from! ...Like, there are a few transactions I didn't make...? But I don't know, maybe Asmodeus or some other prince just has the info!" The crow says.

"...a few transactions? Like what, out of curiosity, if you're willing to tell us of course." Luna asks.

“Hmmmm...” Knight says.

"Uhh… Mostly cryptocurrencies and gambling websites for popular online FPSs." The crow responds.

"Oh gods a CSGO Lotto nerd." Luna sighs.

“Oh god.” Knight says.

"Ewww cryptobros." Luna says.

"It's not even like.. good nfts? or cool ones? ...Shit taste." The crow says.

"Oh gods they bought the color blue, didn't they?" Luna asks.

"Worse. The color piss yellow." The crow responds.

"Oh my gods..."

“OH GOD-” Knight says.

The crow begins scrolling through the bank account transactions history. "Yeah, apparently whoever uses this account has been following Twitter trends from the overworld???? Like. Even had a GameStop phase. What the hell. Biggest transaction is still that crackhead Wrath demon who asked for like... 10 billion dollars."

“That’s probably Cole.” Knight says.

"Most likely." Luna says.

"Probably...Uhh... Leviathan and Legion used it once after Mammon died. After that, all anon." The crow says.

“Hmmm….” Knight says.

"Interesting." Luna comments. "Wait what the heck would Leviathan even buy?"

"Good question. Was actually taking money out of the account!" The crow responds.

“Huh.” Knight says.

"Y’knoww... cash." The crow says.

"Hmm. And I'm guessing Legion bought the Library then?" Luna asks.

"Bought the library?" The crow snickers. "No, that'd be silly. He bought a lockbox."

“Interesting, do you know where said lockbox is?” Knight asks.

"N-no..??? I'm just the money guy!! I haven't left this cage in years!!!"

"Oh jeez, poor guy," Luna says.

“Okay…..Thank you for your time.” Knight says.

"Thank you so much," Luna says.

"You're welcome!"

"Okay, where else. There's that femboy crow serving drinks." Luna says.

“We could try finding that door,” Knight says.

"Bet." Luna looks for that door, the one that requires the object.

She can’t see anything like it in the room, but there's a very small turn towards a little cove behind the tophat crow's area.

Luna goes towards that cove.

Knight follows Luna.

Seems like a dark hallway cut incredibly short by a sudden wall. A part of that wall is pushed an inch farther back than the rest and has a cut directly in the middle of it. Presumably that keyhole.

Luna inspects the keyhole. Does it have any special shape to it?

Definitely. It isn't a keyhole at all. It's as if someone had stabbed a blade directly into an unsolidified mold.

"...that's weird as hell. I'm beginning to have doubts an antler's gonna work here. This is looking to be some specific knife or sword." Luna says. "Do we know if Mammon or Legion ever had a sword?"

“I don’t think so,” Knight responds.

It's worth noting that the shape of the blade is very distinct. Like a cut gem that got sharpened and turned into a weapon.

"...hmm. The shape of this is super interesting. It's like someone made a diamond blade or something. Like the kind Jeff Bezos would make if he were insane, oh wait. Alright, guess we gotta find ourselves a gemstone sword/knife." Luna returns to the main casino floor, unsure where to go next. Knight follows.

There is definitely a door available to leave, games to gamble on, and the staircase into the library.

“It looks like we’ve hit a dead-end,” Knight says.

"Yep, you choose. Hang on, would Legion have any idea? We can ask in the Kiss server." Luna says.

“That’s what I was planning to do later and let’s head home for now.” Knight says.

“Ok.” Luna follows Knight.

Luna opens the door with her key. The door opens up to the guest bedroom and they head home.
