We are slowly building the world of a past campaign.
Context: We recently started a new campaign with the same group of players who were playing in the campaign we just finished. The current campaign takes place in the same world, but like 200 years in the past, before the events of the old campaign. The party (Half-Elf Wild Magic Wizard, Human Fighter who was raised by Orcs, Incubus Druid who was assigned to be our babysitter, Yuan-Ti Rogue) has just gone through a ridiculously silly dungeon to farm XP and get gold and somehow ended up back in the bar in the town. Only the Wizard and the Rogue(me) passed the will save to realize we were still in the dungeon.
Wizard: (As I’m trying to figure out what the heck is going on with this bar) I’m going to go to the bathroom to try and look for anything weird.
DM: Okay, you walk into the back hallway and see several doors-One medium sized male door, one medium sized female door, one medium sized ambiguous door, one large door, and one small door.
Wizard: I open the medium male door.
DM: You walk in and instead of seeing the usual latrines you’re used to, you see what looks like a modern toilet with the porcelain and the handle and everything.
Wizard: I inspect this weird contraption!
DM: As you’re looking at it, you toggle the handle and flush the toilet. You’ve never seen anything like this, so you’re pretty freaked out.
Wizard: I start tearing apart the toilet and scream, “SHOW YOURSELF, TINY SORCERER!”
The rest of us hear him and, while the Druid tries to contemplate his existence and the Fighter picks fights with the bar patrons I go to check on him.
Rogue: What is wrong with you?
Wizard: I’m trying to find the wizard behind this contraption! Watch! *flushes the toilet again*
Rogue: *shocked, but too tired and busy trying to figure the illusion out to give too much of a damn* You…I don’t even care… *walks back out into the bar while the Wizard continues trying to find the magic user he’s convinced is making the toilet work*
DM: (OOC) So, by the way, this is where Brinna gets the idea for the Toy-Rey she showed your other characters in the old campaign, your stories of this bar bathroom.
