Jesus Syringe
The Jesus Syringe is a simple pump device consisting of a cylindrical tube (called a barrel) with a little rubber figure of a messiah suspended inside of it & a sliding plunger also inside it that expels a clear liquids through the nozzle. This item originally belonged to Gorm, but he simply gave it up to the player characters. It was then won in a bet from them by Mushroom Guy.
The real world backstory of the Jesus Syringe goes like this. Many little rubber Jesus figures had been circulating in the local area where all the actual players live. One was found sitting near a tea urn in the backroom of a restaurant, by the Dungeon Master. It then spent about 6 months in his car, largely forgotten about even though he told himself that it'd be amusing to use as a minifigure in this campaign. Finally he remembered it existed and put it in his pocket to whip out as a random NPC at a game session.
Before he could “inject” it into the game however a vet tech who is a player in the game commented randomly that at their veterinary workplace they have what they call a “Jesus Syringe”. The context of that of course implies some strong drugs for better or worse for injecting into pets. But the timing of this comment on this fateful game session was too perfect given the figure was in the DM's pocket already. So not long thereafter the player characters encountered someone camping along a road side, and near their tent as they snuck up on it they found the syringe. Naturally the NPC in the tent, who would end up being named Gorm, was represented with the Jesus figure. Thus Gorm's item left on the ground near his tent was the Jesus Syrgine because the timing was perfect to somehow work all of these elements together.
We don't actually know what the Jesus Syringe does in this fantasy campaign setting, but maybe one day we will find out.
