Okay, so!
tsundelta and
pedokinesis have a little... history together regarding Halloween. More specifically, at their last game, tl;dr, they ran a mansion halloween party, cut the lights and locked the doors at midnight, and filled the whole place with (fake) corpses, stealing the real people and hiding them off for the night. The surviving would be locked in the mansion, either in fear that it would strike again or the detective types would try to solve the mystery of whodunnit and why.
That Halloween was easy mode. It was easy to pass off on the setting (which would do random things like that) come morning, so the culprits were never officially caught or named. Let's say the two want to up the ante this Halloween (or close to it, a party is a party.)
Here's a brief timeline of things going down as I'm imagining it? I am running this by you first, Kev!
• I'm assuming with the last party and how many were able to figure out that there were two people behind it, Lambda and Hyobu will want to keep their hands out of it as much as possible. AKA not appearing to be involved with the party at all. Lambda will probably suggest to him that he announce it under an alias and disguise, and that she'll do something of the same nature when setting up the party area.
• She'll be gunning for full disguise mode. GB has a lot more threatening disguise-revealers so she's going to be doing this as completely stealthy as possible. And she knows Hyobu can do his stuff.
• They'll announce it a week or so before. Costume party, free food and drinks. Lambda might go so far as (disguised) forwarding credits to companies so that people can have a paid day off to attend. I'm sure everyone will think it's pretty fishy, but if they can get into the system, they're good.
• RE: Hyobu's disguise-- do we clean slate fake someone or do we plot with and kidnap someone for a month and pose as them? Thaaaat is up to you!
• It'll play out similarly, but probably less victims. Similarly, why don't we knock them out and put them away in magical storage land instead of let them be awake? That way they have no memory of the event at all.
• Should we 'kill' them all at once, or by the hour? Last time we did it all at once. It might be more believable (keeping in mind there's Sherlock characters at GB....) If they vanish one by one.
• I imagine these two would up the ante since they're playing with a harder crowd. More fun for everyone... eeeespecially vicious trolls trolling poor innocent people.
• The only reason I'm not suggesting actual killing this time around is because of the kill system in place. Otherwise, Lambda would go for that.
